In an otherwise excellent article <[email protected]> on the
Japanese space program, [email protected] (Jim Kempf) says:
> ... there is no well known international astronomer of
> Japanese origin and a very weak astronomical program in general.
It is not clear whether this statement is from Mr. Kempf or from
the article he is quoting, but I have to dispute at least the second
part. While Japanese astronomy is arguably weaker than it ought to be
considering the strength of the Japanese economy, describing it as
"very weak" in absolute term is too severe.
The Japanese astronomy community is small but excellent in certain
areas. While Japan has no large optical telescopes, they do operate
the world's largest millimeter-wave telescope (45 meters) and a
world-class millimeter interferometer. These instruments, used by
both Japanese and foreigners, have made major contributions to
understanding of molecular clouds and star formation. Japan (ISAS)
has also launched two X-ray satellites, one of which (GINGA, I think)
made the first X-ray detection of the Large Magellanic Cloud Galaxy
supernova, 1987A. Also notable were the Halley's Comet flybys.
While no Japanese astronomer is publicly recognized (at least in
this country), many are well known to other astronomers and are highly
respected. The term "Hayashi track", for example, is known (or ought
to be) to all astronomers.

| re .0
The 'problems' paragraph has a number of problems of its own.
The LE-5 LOX/LH2 engine is a Japanese design, not a US design built
under license. In fact, McDonnell Douglas tried to buy the rights
to build and use the LE-5 in an enhanced Delta II! The Japanese
refused on the basis that there would be no guarantee that the vehicle
would not be used for military purposes (SDI).
They DO have solid rocket capability. Their first satellite was
launched by a Lambda 4S, an all solid propellant vehicle with similar
capabilities to the US Scout. They currently fly Mu 3S-2, the latest in
a long line of solid propellant launch vehicles. They also build the
strapon motors for the N series and H-1 launch vehicles (probably under
license to Thiokol).
Planet A was launched on a Mu 3S, which probably doesn't lend itself
well to other than direct injection trajectories for planetary
missions.
Unfortunately, these kind of mistakes make me wonder about the accuracy
of the rest of the article. I always thought one of their major
problems was competition between ISAS and NASDA. This is the case
in launch vehicle development.

This sounds to me like somebody has gotten a bit confused; it's
the *first* stage of the H-1 that is made under US license, since it
is basically a Delta. The second stage is pretty much all-Japanese.
McDonnell-Douglas, which makes Delta, tried to get US rights to the
second stage; the Japanese refused to sell.

Now I know somebody is confused. Ariane is indeed 3 stages, but
the US boosters cover the range from 2 to 4 stages.

Again something has been lost somewhere; as I understand it,
Planet A used direct injection simply to get maximum payload out of a
booster that was rather small for a planetary mission.

Also note that once a shuttle with cargo capacity of 2 metric tons
is flying with frequency, all it takes to provide a major space effort
is a large booster. The US ought to be seriously worried soon.

| Bubble Is Burst on Japanese Shuttle
[from Insight magazine, Nov. 7, 1988]
The successful flight of the Discovery has put the United States'
shuttle program back on track, but Japan's attempt to build a reusable
shuttle is not faring so well. In September, a scale model of the
Japanese HOPE shuttle plunged into the sea and was lost during a
crucial flight test.
Scientists at Japan's Institute of Space and Astronautical Science
attached the 400-pound, unmanned vehicle to a large balloon at the
Kagoshima launch center and planned to have the balloon carry it to an
altitude of about 12 miles. There, a booster rocket would separate,
leaving the model to glide back to Earth. However, the balloon broke
on the way up, and the craft plunged into the sea before any kind of
rescue mission could be mounted.
Japanese space scientists have not said how much of a setback this is
for the program. They had hoped to fly a full-scale shuttle as early
as 1996.

Japanese Satellite
The first Hughes 393 communications satellite is owned by the
Japan Communications Satellite Co. (JCSAT) and is scheduled to
be launched Feb 28 on an Ariane 44LP rocket to provide the first
privately owned satellite communications in Japan.
[Was the satellite launched? --mjt]
The spin stabilized JCSAT 1 is 12 ft in diameter, 32.0 ft long
with the antenna and telescoping solar cells deployed. It will
weigh 3,000 lbs in orbit. Solar arrays will provide 2,350 w.
at the beginning of the satellite's 10 year life, supplying 32
Ku band transponders with 27MHz of bandwidth. The satellite will
be in geosynchronous orbit at 150 deg, E. longitude and is to
start service in May. A second JCSAT is planned for launch this
summer by a Martin Marietta Titan 3 rocket.

Japanese HOPE Orbiter Planned for 1996 Launch
The Japanese are planning to use their unmanned HOPE orbiter as a
research and development springboard towards the construction of
a horizontal takeoff and landing, single-stage-to-orbit aerospace
plane. The National Space Development Agency of Japan (NASDA) has
been leading the research and development effort for the winged
orbiter, which is scheduled to be launched atop Japan's H-2
booster in late 1996. Once operational, the vehicle will be
capable of reaching the multinational FREEDOM space station after
launch from the Tanegashima Space Center.
In its current configuration, the HOPE is expected to be 11.5m
(37.7ft) in length, 2.3m (7.5ft) in width, 2.5m (8.2ft) in height,
weigh about 8.8 tons at launch, and have a payload capacity of
about 1.2 tons. The wing span is expected to have a 6.24m
(20.5ft) span and a leading edge sweep of 48 deg. The fuselage has
been sized to accommodate a cargo bay large enough to handle three
space station standard rack containers in a nonpressurized environment.

I do not know the exact trajectory that Muses is taking but it is
possible that it is not going directly to the Moon like most lunar
probes. The purpose of this mission is basicly an engineering study to
control distant spacecraft and to better determine orbits. What could
be happening here is that Muses will make several very elongated orbits of
the Earth before finally encountering the Moon. This way the Japanese
can track the orbit of the spacecraft for a few orbits and "play around
with it" a bit before the relatively demanding lunar encounter.

| Japan's first lunar probe lifted off today at 8:46 p.m. (6:46 a.m.
EST) on an M3S-2 rocket from its Uchinoura space center.
If successful, the Muses-A satellite will be the first spacecraft
to visit the Moon since the unmanned Soviet LUNA 24 vehicle landed
on its surface in 1976 and returned soil samples to Earth. Only the
United States and the Soviet Union have sent spacecraft to the Moon.
Originally set for Tuesday, the liftoff had been postponed with
only 18 seconds to go after an electrical switching problem cut off
power to a hydraulic pump used to aim the nozzle of an auxiliary
booster rocket. Mission chief Hiroki Matsuo said Tuesday's delay
was the first time in five launches of the solid-fuel M3S-2 that
the countdown had been stopped in the final 60 seconds.
The three-stage red-and-silver M3S-2 rocket, which cannot lift
much more than its 400-pound payload, is to carry Muses-A into an
elliptical orbit that will bring it to within about 10,000 miles of
the Moon in eight weeks. The Nissan Motor Co., Japan's second-largest
automobile maker, built the three-stage, 62-ton M3S-2 engine used in
the lunar mission.
Just before crossing the Moon's path, a smaller satellite will
break off the Muses-A and go into lunar orbit and send data to the
larger satellite on temperatures and electrical fields.
"This time we are going to the Moon; but our objective is not
the Moon itself," Matsuo said. "Our institute is getting into
interplanetary missions in the 1990s and for that we need to
refine our technology."

The SW&ST article I read said that the spacecraft was actually going to be in
a very elliptical Earth orbit. This orbit was to be sufficiently elongated
as to intersect the path of the moon. I don't think the article explicitly
stated, but I presume, this is to reduce the thrust required to reach the
moon. A direct (Earth-escape) trajectory requires more power.

| According to the NY Times (15-JAN) If everything goes according to plan
the two satellites aboard the solid fuel rock will approach the Moon on
the 18 to March and use the Moon's gravity field to catapult the larger
of the two satellites ino an elliptical orbit that will haed it back
towards Earth and then to the Moon again. Just before crossing the
Moon's path, the smaller satllite, only 14 inches in diameter will
break off an begin circling the Moon to test sytems that Japan hopes to
use to sen other sceintific instruments, including a lunar seismometer,
to the Moon,s surface in the 1990's.
The project was done on a shoestring budget of about $41 Million, a
small group of Japanese scientist sent two satellites aflot at 8:46 PM
or 6:46 AM New York Tim.

| I unfortunately know zero about orbital dynamics. From inspection
of their orbit, it seems a cheap way to drop things on the moon.
Can things be easily detached at either end of an elliptical orbit?
Can something in such an orbit act as a sort of "shuttle" between
earth and moon? For example, a station that you dock with on the
earth side of the ellips, then brake away from on the moon side.
Or is this an impractical idea?

| If you just have a platform of some sort in an earth-moon orbit with no special
means of acceleration or decceleration, I don't think it would help much as
an earth/moon shuttle. The reason is that in order to "catch" the shuttle
you have to rendezvous with it. In order to rendezvous, you have to accelerate
to its velocity. Once you have done that, you don't need the platform to help
you get to the moon. You will go there anyway. If you expect the platform
to pull you up to speed, you will somehow need to supply the energy. Therein
lies the challenge. Supplying energy cheaply. Just having the spacecraft
does not do that.

Organization: The Internet
It was just announced that the Munich Dust Detector aboard the
Japanese MUSES-A spacecraft didn't measure any increase in dust
density when it passed the L4 Lagrange Point of the Earth-Moon system
on February 14. However, since it is a fairly small detector the
counting rate is very small (about one dust grain per week!) and thus
the statistics are not convincing.
In the past three decades there has been a lot of controversy
about the possibility that there are "dust moons" at the L4 and L5
points, and one Polish researcher even claimed to have seen and
photographed them. [Some references: Kordylewski, Acta Astron.

Kordylewski, Sternenbote _21_,81{1978}]
The 'phenomenon', if there is any, is very little known nowadays,
and I wonder: Has it been 'killed' convincingly, either by
calculation or by complete non-observation (references, please!,) or
was it just forgotten? What does the 'L5 society' think about it?

Japan's first lunar satellite, Muses-A, completed two missions, a
swing-by flight designed to boost its speed and enlarge its elliptical
Earth orbit, and the placement of a smaller satellite in lunar orbit.
The satellite, nicknamed Hiten, or Space Flyer, conducted its
first lunar swing-by after approaching within about 9,100 miles of
the Moon. The satellite will conduct a total of eight swing-bys,
four acceleration and four deceleration flights, during its flight.
Hiten, a cylindrical satellite, 33 inches in height and 4.6 feet

According to Dr. Uesugi, head of MUSES-A project, Hagoromo's
transmitter failed before Hiten's first flyby. So the rocket firing
of Hagoromo for putting into lunar orbit was optically confirmed
through the Schmidt camera (105-cm, F3.1) of Kiso Observatory, Japan.

RELEASE: 90-106
NASA AND JAPAN AGREE ON NEW AREAS OF SPACE COOPERATION
NASA and Japan's Ministry of State for Science and Technology
agreed to new areas of space cooperation during a Senior Standing
Liaison Group (SSLG) meeting held in Tokyo, July 26. NASA
Administrator Richard H. Truly and Minister Tomoji Oshima, Ministry of
State for Science and Technology, co-chaired the meeting.
The following are the new NASA/Japan projects:
o Observation of the Ozone Layer -- NASA will fly a Total Ozone
Mapping Spectrometer (TOMS) instrument and the Environment Agency of
Japan will fly the Improved Limb Atmospheric Spectrometer and the
Retroreflector in Space on Japan's ADEOS spacecraft to measure
atmospheric constituents. ADEOS, the Advanced Earth Observation
Satellite, is scheduled for launch in 1995. NASA and the Environment
Agency of Japan will exchange data between the two agencies'
instruments and continue research on a comparison of ground-based and
satellite data.
o Space Environment Monitoring -- Data will be exchanged between
NASA, NOAA and the Communications Research Laboratory (CRL) of Japan
using NASA's Space Physics Analysis Network (SPAN). CRL was connected
to SPAN in 1989 and plans to receive real-time solar wind data from
future NASA missions.
o Space Station Solar Terrestrial Physics -- NASA and Japan's
Institute of Space and Astronautical Science will continue discussions
on use of the Neutral Environment with Plasma Interactions Monitoring
System and other systems to measure the solar-terrestrial environment
from Space Station Freedom.
o Space Microgravity Experiments -- NASA and the National Space
Development Agency of Japan will continue cooperation in microgravity
science on Space Shuttle Spacelab missions. The first Japanese payload
specialist, Dr. Mamoru Mohri, will fly onboard Spacelab-J in 1991.
During the meeting, Administrator Truly and Minister Oshima also
discussed the ongoing cooperation between the two countries on the
construction and utilization of Space Station Freedom. They emphasized
the importance of adequate funding for the project in both countries
and agreed on the importance of Japan's gaining manned spaceflight
experience in preparation for it.
Additional areas of discussion included joint projects in X- ray
and infrared astronomy, cosmic ray research, the study of ocean
dynamics, measurement of cloud height by satellite stereography,
reception of Japan's first Marine Observation Satellite data and
satellite measurements of tropical rainfall.
The SSLG was established in 1979 by NASA and Japanese government
space agencies. Senior-level NASA and Japanese space officials have
met in the SSLG on a periodic basis to review cooperative projects.
The next meeting of the SSLG will take place in the United States.

Hiten Update
July 31, 1990
Japan's Moon probe, Hiten, made its second lunar flyby on July
10. The probe was launched into Earth orbit on January 24, 1990. It
was then known as MUSES-A, but was renamed to Hiten once in orbit.
The 430 lb probe looped out from Earth and made its first lunar flyby
(within 9,100 miles of the Moon) on March 19, where it dropped off its
26 lb midget satellite, Hagoromo. Japan became the third nation to
orbit a satellite around the Moon, joining the Unites States and USSR.
Hiten is currently traveling at 2,237 mph on an oblong path
around Earth, picking up lunar gravity assists as it swings by the
Moon. The third lunar flyby is scheduled for August 4. Aboard Hiten
is a West German micrometeorite counter which records weight, speed
and direction of dust particles striking the spacecraft.
The smaller spacecraft, Hagoromo, will remain in orbit around the
Moon. An apparently broken transistor radio caused the Japanese space
scientists to lose track of it. Hagoromo's rocket motor fired on
schedule on March 19, but the spacecraft's tracking transmitter failed
immediately. The cross-shaped antenna on the 1-foot tall Hagoromo was
supposed to allow radio contact with controllers on Earth. Japanese
astronomers were able to see Hagoromo orbiting the Moon using large
optical telescopes. Hagoromo is probably doing its job of recording
temperatures and electrical fields around the Moon, but is unable to
transit the data to Hiten for relay to Earth.

Subject: The 'Hiten Update 31 July 1990' was right!
Several netters had questioned the Japanese report that
astronomers have observed the tiny Hagaromo subsatellite of Hiten in
its lunar orbit. As reported in Nature Vol.346 (2 Aug 1990) p. 400,
however, the story was *almost* correct:
] ISAS called on astronomers throughout Japan to train their telescopes on the
] Moon on 18 March, when the lunar orbiter's tiny engine was fired after it had

INTRODUCTION
1.1 Foreword
The National Space Development Agency of Japan (NASDA) will launch the
Broadcasting Satellite-3a (BS-3a) via an H-I launch vehicle (H22F)* either in
August or September 1990. This material provides the following explanations:
(1) Launch program of H22F carrying the BS-3a, extending to third
stage/satellite separation phases and their confirmation.
(2) Satellite tracking and control program, including the launch phase in
which the BS-3a preparatory operations for tracking and control are carried
out, as well as the initial phase consisting of injecting the satellite into
drift orbit, then into a geostationary earth orbit (GEO), and functional
checks of the satellite's on-board equipment after its injection into GEO.
* Serial flight number from the first N-I launch vehicle at Tanegashima
Space Center
1.2 Objectives
The objectives of the mission are to launch the BS-3a by H-I launch vehicle,
and to track and control satellite for operational use by user organizations.
BS-3a was developed to take over broadcasting services from BS-2 and to meet
the increasing and diversifying broadcasting demands as well as to establish
the advanced satellite broadcasting technology.

2.2 Flight Plan
The H22F carrying BS-3a will be vertically launched from the Osaki
Range of the Tanegashima Space Center. The launch vehicle will incline
its vertical pitch plane at 92.5 degrees of the planned initial launch
azimuth from the north, and fly the trajectory over the Pacific Ocean.
The strap-on boosters and the first stage will be separated 85 seconds and 278
seconds respectively after lift-off. Second stage engine cut-off will occur
645 seconds after lift-off upon receiving a command from the on-board guidance
equipment, and the launch vehicle will be injected into the planned parking
orbit. It will then stabilize its attitude for the third stage motor ignition
for injection into transfer orbit during its inertial flight.
The third stage will be separated from the second stage above the equator.
The third stage motor will then be ignited, and the third stage and satellite
will be injected into the planned transfer orbit. The satellite will be
separated from the third stage, at an altitude of 190 km, at 2 degrees S.
latitude and 149 degrees W. longitude.
2.3 Satellite
2.3.1 Outline
Broadcasting Satellite-3a (BS-3a) will continue the technological development
of satellite broadcasting and satisfy the existing broadcasting service
requirements. BS-3a is scheduled to be launched in August 1990 into a
geostationary orbit at 110 degrees east longitude. The satellite is a
three-axis stabilized box type satellite and will succeed Broadcasting
Satellite-2 (BS-2). BS-3 differs from BS-2 and has the improvements described
below:
(1) The following subsystems were developed using Japanese technologies:
.. Communications subsystems
.. Telemetry, tracking, and command subsystem
(2) The following improvements enable transmitting more complete and stable
radio waves:
.. Increased the broadcasting channels: 2ch to 3ch
.. Increased TWT output power: 100W to 120W
.. Improved reliability: Common spare system to complete spare system (full
redundancy)
.. Extended service life: 5 years (target) to 7 years
.. Increased gain by improving the antenna pattern
.. Installed wide-band transponder
(3) Employment of the apogee kick motor (AKM) produced in Japan
The domestically produced AKM, partially modified for the BS-3, has been
flight-proven on the Engineering Test Satellite-V (ETS-V).
2.3.2 Missions
The BS-3a missions are listed below.
(1) Broadcasting three TV channels
Three TV transponders are installed onboard BS-3a to enable broadcasting on
three channels, BS channels 3, 7 and 11.
BS channels 7 and 11 will be used by Japan Broadcasting Corporation (NHK)
while the BS channel 3 will be used by Japan Satellite Broadcasting Inc. (JSB).
(2) Experiments with a wide-band transponder
A 20W, wide-band transponder is installed onboard BS-3a in addition to the
broadcasting transponders. Experiments for future broadcasting such as high
resolution image transmission will be conducted.
2.3.3 Overall configuration and major characteristics
BS-3a is designed to have overall configuration and weight adaptable for the
H-I launch vehicle. The BS-3a is manufactured based on the Satcom 3000 bus
series of General Electric Co., Astro-Space Division in U.S.A. The BS-3a
configuration consists of a box type main body which is composed of six
aluminum honeycomb panels having a center cylinder and large solar paddles.
The satellite is approx. 15m long (after the solar paddles are deployed) and
3.2m in height (including antenna section), and the box section measures 1.3m x
1.6m x 1.6m. Its dimensions at launch with the solar paddles folded in are
3.2m x 1.6m x 1.6m which is suitable for the H-I launch vehicle fairing.
The equipment layout of the BS-3a is decided by integrally considering the
visual field of the sensors, operability during assembly and checkout,
maintainability, and interchangeability as well as the thermal, electrical and
mechanical conditions such as heat generation, thermal and electric loss of the
equipment, and balance.
Since the communications subsystems generate much heat, they are installed
on the northeastern and southwestern panels, and antenna panel.
The broadcasting antenna is installed on the antenna panel so as not to disrupt
the patterns due to the interference by equipment other than the antenna.
An improved Satcom 3000 bus series is utilized for the BS-3a.

Japan's Insitute of Space and Astronautical Science decides to
initiate development of an Atlas-class booster for science payloads.
This will be a further upgrade of ISAS's current M-3S-2 solid booster,
a design which has already had many incremental updates [and is now
somewhere in between Scout and Atlas in capacity]. First flight 1994,
carrying a spacecraft for VLBI radio astronomy. Launches will
continue to be from Kagoshima.
ISAS is planning several other astronomy and geophysics missions
meanwhile, and is looking at using the M-5 for Mars/Venus orbiters and
a lunar mission carrying several penetrators. The long-term plan is
to develop a series of M-5-launched spacecraft, so that each major
space-science discipline will have a mission every five or six years.
[Resemblance of this to the Solar System Exploration Committee's
"Planetary Observer" series, largely dead at the hands of NASA and
Congress, is probably not accidental... It looks like the Japanese
recognize a good idea when they see one.] Early development work for
the lunar penetrators is already underway; three of them would be
launched from a lunar orbiter.
The Muses-A mission required some emergency revisions after an
unexpected error in final velocity from the M-3S-2, which put the
orbit rather short of the Moon. (The error was only about 50 m/s, but
that's a lot out there.) The Hiten mother craft expended a fair bit of
its control fuel fixing the orbit. A further problem appeared when it
became clear that the Hagoromo lunar-orbiter subsatellite had
experienced a transmitter failure before separation; lunar-orbit
injection was confirmed instead by infrared photography (from two
ground sites) of its rocket plume. Hiten has since made another lunar
flyby, and will make several more before its mission ends; its primary
purpose is to give Japanese engineers practice in such maneuvers.
Major joint project in Japan (three government agencies and
thirteen companies) is near completion of development on a reusable
spacecraft meant to carry technological experiments up for long stays
in low orbit. It will be launched by the third H-2, and recovered by
a US shuttle mission six months later, on its first mission. (There
are doubts being raised about later flights, given the high cost of
more H-2 launches.) Experiments on the initial flight include various
materials-processing packages, a large-space-structure deployment
test, an infrared astronomical telescope, and a flight test of a
magneto-plasma-dynamic thruster for possible use on future spacecraft.
NASDA postpones launch of the BS-3A broadcast satellite at least three
weeks due to a helium leak in ground-support equipment at Tanegashima.

ISAS discloses that the Astro-C, aka Ginga, X-ray astronomy
satellite is losing altitude more quickly than expected, and has been
since around the start of the year. Intense solar activity is blamed.
At this rate it will reenter within a year. It was launched in 1987
for a nominally one-year mission, but is still active.
NHK (Japan Broadcasting Corp) decides to launch its BS-3A tvsat
without insurance. Launch is set for late August on an H-1. Reasons
for the decision were undisclosed, but satellite insurance is
expensive and NHK has been criticized lately for financial losses.
Soviets say they now have adequate data on free-fall effects for
periods of up to a year, and do not immediately plan any more very
long stays. Mir crews will be up a mere six months each for the next
couple of years. [For those who aren't aware of it, the US record is
three months aboard SKYLAB in 1974.] Mir crews in the near future
will include a lot of guest cosmonauts, who will go up with a new crew
and back down with the old one. This December the Japanese TV
reporter will fly. Next summer's crew has the British Juno cosmonaut
pencilled in, despite Juno's funding problems. The late-1991 crew
will have the Austrian cosmonaut, and the mid-1992 crew the next
French cosmonaut. All are paying customers.
Long story on Japan's first shuttle astronaut, Mamoru Mark Mohri,
now in training for the Spacelab J mission late next year. Two more
Japanese shuttle astronauts are set to fly on International
Microgravity Lab missions in 1993 and 1995. NASDA values these
missions particularly for the flight experience they will contribute
to design of the Japanese space-station module. The Japanese
astronauts say they already have one problem to report with the
Spacelab J hardware: It is too heavily automated, leaving little
possibility of manual troubleshooting in case of difficulties. "All
we can do is shut it down." They also say that NASA's post-Challenger
safety-documentation requirements are excessive and are interfering
with mission planning. [Lots more details on the experiments to be
flown. - HS]
Details of ISAS's next two major scientific satellites: Solar A,
for launch late next year, with the first solar imaging equipment to
beat the capabilities of Skylab's solar telescope [from 1973], and
Geotail, a solar-wind probe with very long antennas, a joint ISAS-NASA
project for launch on Delta in mid-1992. [Details on experiments.]
Descriptions of the Japan's next two astronomy satellites, Astro-D
(1993) and Muses-B (1995). Astro-D will carry an X-ray telescope with
much better sensitivity and spectral resolution than existing ones.
Muses-B will be a radio observatory for VLBI work together with
ground-based receivers. Both will be launched from Kagoshima, Astro-D
on the last M-3S-2 and Muses-B on the first M-5. Both missions are
international collaborations, with NASA supplying the X-ray telescope
for Astro-D and various nations planning radio observations in
conjunction with Muses-B. Both also present design challenges, with
Astro-D's telescope having to telescope [!] to fit under the M-3S-2
payload fairing, and Muses-B's 10m dish presenting problems in both
antenna deployment and precise attitude control of a flexible spacecraft.
Story on Japanese studies, both government and commercial, for
autonomous space stations, lunar bases, and advanced concepts for both
launch and in-space propulsion. One project of note is work on
electric propulsion for deep-space missions, notably the Jupiter
probes specifically mentioned in Japan's new government space policy.

| 11/29/90: REVIEW OF U.S./JAPAN SPACE COOPERATION
RELEASE: 90-156
NASA and the Space Activities Commission of Japan (SAC) held
a series of meetings in Arlington, Va., during the week of Nov.
26, culminating in the fourth meeting of the NASA/SAC Cooperative
Space Activities Planning Group on Nov. 29.
The Cooperative Space Activities Planning Group meets
annually to review ongoing space cooperation between the U.S. and
Japan. Discussions focused on a number of collaborative projects
in the fields of astrophysics, solar system science, microgravity
science, life science and Earth observation. The meeting was co-
chaired by Dr. Lennard Fisk, NASA Associate Administrator for
Space Science and Applications, and Mr. Katsuhisa Ida, Director-
General, Research and Development Bureau, Science and Technology
Agency (STA) of Japan.
During the week, Ida met with senior NASA officials,
including Richard H. Truly, NASA Administrator. During these
meetings, the following cooperative proposals were discussed:
o NASA Associate Administrator for Space Flight Dr. William
B. Lenoir affirmed to Ida that two Japanese candidates are
invited to join the next NASA Mission Specialist training class,
beginning in July 1992. The Japanese Mission Specialist
candidates will participate in training on the same basis as U.S.
Mission Specialist candidates at NASA's Johnson Space Center,
Houston. It is NASA's intent to offer a Space Shuttle flight
assignment to one or both of the Japanese Mission Specialist
candidates in the years following the successful completion of
the training program.
o NASA and STA are actively reviewing options for flying
Japanese Experiment Module (JEM) hardware on a Space Shuttle
mission in the mid-1990s. The JEM is Japan's contribution to the
Space Station Freedom program. The purpose of such a Shuttle
flight would be to demonstrate in space a key element of the JEM.
o NASA also offered Japan an opportunity to send Japanese
engineers to work and train in the Mission Operations Directorate
at the Johnson Space Center during mission preparation and
operations activities for the Spacelab-J mission. This will
enable Japan to obtain additional flight operations experience
prior to the Space Station era.
The next meeting of the Cooperative Space Activities
Planning Group will be next fall in Japan.

390.38 | Japanese GINGA detects powerful quasar burst | ADVAX::KLAES | All the Universe, or nothing! | Mon Jan 14 1991 16:33 | 104 |
| From: [email protected] (WILLIAM HARWOOD, UPI Science Writer)
Newsgroups: clari.tw.space
Subject: Explosive quasar eruption seen
Date: 14 Jan 91 16:58:07 GMT
Astronomers Monday announced the discovery of a record eruption from
a quasar 2 billion light years away, an unimaginable three-minute burst
of energy that, when viewed from Earth, rivaled the total output of the
sun over nearly 1 million years.
``Quasars, even in their quiet state, are really mind boggling in how
much energy they radiate,'' said astronomer Ronald Remillard, co-author
of a paper on the flare presented Monday at a meeting of the American
Astronomical Society in Philadelphia.
``That's just part of why so many astronomy researchers are working
on trying to really nail down the last secrets about them because it's
just phenomenal what they do.''
A Japanese satellite named ``Ginga'' -- Galaxy -- recorded the X-ray
burst from quasar PKS 0558-504 in the constellation Orion at 8:12 p.m.
EST Nov. 13, 1989. The quasar is believed to be 2 billion light years
from Earth, so far that light, traveling 186,000 miles per second, took
2 billion years to cover the distance.
The announcement of the flare discovery was made Monday after
extensive analysis to make sure the unusual signal was real.
The discovery was made by graduate student Bruce Grossan, Remillard
and Hale Bradt, all of the Massachusetts Institute of Technology in
Cambridge, Mass.; Takaya Ohashi of the University of Tokyo; and Yasuo
Tanaka, Kiyoshi Hayashida and Fumijoshi Makino, all of the Institute of
Space and Astronautical Science in Sagamihara, Japan.
Remillard said the signal detected by Ginga indicated a record three-
minute eruption equal to the sun's total energy output over nearly 1
million years, assuming the outburst was spread evenly in all
directions.
To put that into perspective, the sun produces about 53 million watts
of power each second for every square yard of its surface, enough power
per square yard to light 100,000 average homes.
Put another way, the sun converts 660 million tons of matter into
energy every second. The conversion of a mere 1 pound of hydrogen into
energy through nuclear fusion can power a 100 watt light bulb for 450,000
years.
But when it comes to sheer energy production, nothing in the known
universe rivals the output of quasars, mysterious objects that can be as
small as a single solar system and yet outshine entire galaxies.
It is widely believed that quasars are located at the cores of
distant galaxies that serve as hosts to super-massive black holes,
objects with such tremendous gravity that not even light can escape.
Quasar PKS 0558-504 is thought to have a central black hole with a mass
of at least 100 million times that of the sun.
As gas, dust and other stellar debris falls into such black holes, it
is heated to extreme temperatures. High energy light in the form of X-
rays and gamma rays is emitted before the matter falls into the black
hole, past the point where gravity prevents anything from escaping.
``For the time being, it's certainly taken for granted that the
gravity of a super-collapsed object is about the only thing anyone can
imagine that could power (a quasar),'' Remillard said in a telephone
interview from Cambridge.
But the very energy emitted by material falling into the hole can
produce an outward pressure pushing against the falling matter.
``The natural thing to assume if you see a quasar flare is that,
well, just an extra blob of stuff fell into the system,'' Remillard
said. ``The problem is ... while gravity is pulling things in and
keeping the gas together near the quasar, as you start adding more and
more light coming out of the thing, the light starts pushing on the gas.
It wants to drive stuff outward.''
Calculations show there is a limit to how much a quasar's energy
output can increase in a given period of time ``before you're actually
getting too much light out of the system and it's going to stop the gas
from going in,'' Remillard said. ``The problem with our flare is we
exceed that number.''
But by assuming the flare was caused by matter traveling in the
direction of Earth at a velocity near the speed of light, the
astronomers were able to use the concept of ``relativistic beaming'' to
explain the titanic eruption, based on Einstein's theory of relativity.
``This condition ... may arise if part of the energy of the infalling
matter is directed to the formation of a jet of gas that escapes in a
narrow beam (like a high-pressure hose) before falling too near to the
black hole,'' the researchers said in a news release.
Thus, saying the three-minute flare equaled the output of the sun
over nearly 1 million years is true for observers in the direction of
Earth but might not be true for observers moving alongside the jet.
``It's not entirely smoke and mirrors,'' Remillard said. ``There has
to be tremendous, incredible amounts of energy just to eject something
like this. On the other hand, it's describing something in a way to make
it realistic that's not precise anymore. In our direction it looks to be
this way.''

HITEN STATUS REPORT
March 8, 1991
Japan's small Moon probe, Hiten, made its seventh lunar flyby on
March 3, passing about 13,300 km from the Moon. JPL's Deep Space
Network is tracking the spacecraft. On February 28, the 34 meter
Goldstone antenna supported ranging tests on Hiten, and were
successful. On March 1, the same antenna was used to collect 24
minutes of ranging and doppler data.
Hiten was launched into Earth orbit on January 24, 1990. The
spacecraft was then known as MUSES-A, but was renamed to Hiten once
in orbit. The 430 lb probe looped out from Earth and made its first
lunary flyby on March 19, where it dropped off its 26 lb midget
satellite, Hagoromo. Japan at this point became the third nation to
orbit a satellite around the Moon, joining the Unites States and USSR.
The smaller spacecraft, Hagoromo, will remain in orbit around the
Moon. An apparently broken transistor radio caused the Japanese space
scientists to lose track of it. Hagoromo's rocket motor fired on
schedule on March 19, but the spacecraft's tracking transmitter failed
immediately. The rocket firing of Hagoromo was optically confirmed
using the Schmidt camera (105-cm, F3.1) at the Kiso Observatory in Japan.
Hiten will continue to make lunar flybys on a regular basis,
typically once a month. According to Takahiro Yamada at ISAS, Hiten
will be performing aerobreaking experiments on March 19 and 30. These
experiments will be done using the atmosphere of Earth. The next
lunar flyby is scheduled for April 26.

===================== [Littleton, MA, USA ]
Japanese Space Activities
Japan's Space Activities Commission has approved initiation of the
Comets and Lunar-A programs. Comets is a 2,000 kg research satellite
to be developed for testing advanced communications technologies
between moving vehicles and satellites. It is to be launched in
1997 from Tanegashima Space Center into a geostationary orbit. A
consortium of Mitsubishi Electric, Toshiba, and Nippon Electric is
expected to win the development contract. Lunar-A is to be launched
by the Institute of Space and Astronautical Science in early 1996
on an M-5 rocket. The spacecraft will be placed in a 100 km lunar
orbit and will drop three penetrators to the Moon's surface.
Precision seismometers in the penetrators will transmit seismic wave
data back to Earth via Lunar-A. Nippon Electric is expected to be
the lead contractor of Lunar-A.

>Is there some japanese plan for a lunar geochemistry mapper?
Yes. Japanese interest in such a mission has been rumored for years;
now I have some harder information.
The paper is:
"Study on Lunar Polar Orbiter"
by R. Imai, T. Maeda, T. Eto, K. Ohta, Y. Kaneko, and T. Iwata
Systems Engineering Dept.
Tsukuba Space Center
National Space Development Agency of Japan
2-1-1, Sengen, Tsukuba, 305, Japan
IAF-91-034
It outlines two alternative lunar-polar-orbiter (LPO) systems, each
inheriting much from NASDA's Earth observation satellite series
(MOS-1, JERS-1, and ADEOS). Each would be launched on an H-II rocket
and put about 2 tons in lunar orbit.
The first system, the Mapping Mission, would carry:
--A mapping imager, high-resolution mode: 1m resolution, 5km swath
width, panchromatic
low-resolution mode: 10m resolution, 50km swath,
3 spectral bands
--Synthetic-aperture radar, 20m resolution, 40km swath width
(This is the first time I've seen SAR proposed for a lunar mission.)
--Laser altimeter, 1m resolution if they can get spacecraft pointing
stability to 0.03 degrees
--X-ray spectrometer, 512 channels, 16km resolution, 35km swath
--Gamma-ray spectrometer, germanium semiconductor, 2.5 keV energy resolution
--Other instruments are candidates, including a magnetometer,
radiation monitors, or short-infrared radiometer.
The second system is called the Imaging Orbiter and Landing Probe
Mission. The 1.5-ton orbiter would carry only the mapping imager,
gamma-ray, and X-ray instruments. A half-ton lander would separate
after the initial mapping phase and landing site selection (about 3
months?) and land to "acquire ground truth" with imaging,
thermocouples, and radiation monitor. The lander's major purpose,
however, is to establish Japanese technology for lunar landing.
Orbiter missions would last about 1 year, with 3 months required for
global low-resolution multispectral mapping,
These LPO studies are coupled with NASDA studies of a large and
capable Lunar Mobile Explorer, an unmanned 900-kg six-wheeled rover
discussed by Iwata, Eto, and Kaneko in IAF-91-446, "Lunar Mobile
Explorer: The Variations and the Evolution." LME is equipped with
stereo TV, a laser vaporizer and mass spectrometer to analyze soil, a
sample collector arm, and a furnace to experiment with melting and
processing samples. The teleoperated rover would rest and recharge
its batteries during the periods when the Moon is out of sight of
tracking stations in Japan. Several traverses, of lengths up to 1800
km(!), are being considered. I don't seem to have the speed (I don't
have the paper, just notes on Iwata's presentation), but it's of order
1 km/hour. A data relay satellite is being considered for farside
operation. Later versions of the LME might explore Mars or become
construction and manufacturing robots for a lunar base.
The Big Picture is that NASDA is very interested in exploring the
Moon, certainly cooperating in the Space Exploration Initiative if the
U.S. gets past the paper-rockets stage. They have several studies
brewing of precursor probes, rovers, manned bases, infrastructure,
logistics vehicles-- all the same stuff that the Western aerospace
establishment has been designing and re-designing for years. They
seem to have a bit more emphasis on early materials processing than
typical American plans. There is no official approval for these
projects (where have we heard THAT before?) but they think a 1997
launch for the LPO is reasonable.
With this information, we can update the Lunar Orbiter Mission
Scorecard. I'll post that as a separate message.

The lunar orbiter mission scorecard:
Lunar Prospector, by the Space Studies Institute and Lunar
Exploration, Inc.: Low-energy-resolution gamma-ray spectrometer on
low-cost spacecraft. Design complete, some instruments in hand,
searching for funding (yesterday Allen Sherzer and Edmund Hack
suggested that *NASA* might actually fly it!).
Lunar Observer, by NASA: Keeps getting stomped by Congress; it was
probably a mistake to glue it to SEI instead of putting it in the
planetary-science pipeline. Mapping-quality imaging,
high-energy-resolution gamma rays, laser and radar altimeters, other
goodies. Would use the spare Mars Observer bus. Medium cost. (what,
about $300 million? Started as a low-cost mission and grew.) Hard to
imagine a launch before 1997.
Galileo, by NASA (some German involvement): December 1992 flyby of
Earth will give good imaging of Moon's north pole. Imaging
spectrometer will search for hydrated minerals. Ultraviolet
spectrometer will do limb scans looking for water vapor. I've heard
about a search by starlight for ice in the permanently shadowed polar
regions, but I don't know if this idea has survived into the science
planning.
LPO by NASDA: Now a detailed paper study. The usual gear, plus a
possible synthetic-aperture radar instrument. I don't know how well it
competes with other possible Japanese projects, or how likely it is to
fly. Seems to be tied to landing-site selection for rovers; I suppose
that if LME is delayed, LPO will be kicked into the future too.
Soviet probes: Officials keep mentioning them, but no detailed
proposals have come to my attention. Late Nineties, if ever.
[There was a 1992 Soviet Lunar Orbiter Prospector mission mentioned in
the last few years, based on the PHOBOS spacecraft that went to Mars.
Any updated information on that project? - LK]
ESA interest: Did a study comparable to Lunar Observer around 1977,
died in competition with other ESA science projects. (Planetary
science doesn't seem to swing much weight there. Giotto and Cassini/
Huygens are the only ESA interplanetary projects I can think of.)
More information is welcome, if you have it. I would like to keep up
with any new developments in lunar probes.
Submarines, flying boats, robots, talking Bill Higgins
pictures, radio, television, bouncing radar Fermilab
vibrations off the moon, rocket ships, and [email protected]
atom-splitting-- all in our time. But nobody [email protected]

* SAKIGAKE EARTH SWINGBY *
The spacecraft SAKIGAKE (MS-T5), which was launched from the
Kagoshima Space Center by ISAS on January 8 1985, and approached
Halley's Comet within about 7 million km on March 11, 1986. The
spacecraft is carrying three instru- ments to measure interplanetary
magnetic field/plasma waves/solar wind, all of which work normally
now, so ISAS made an Earth swingby by Sakigake on January 8, 1992 into
an orbit similar to the earth's. The closest approach was at 23h08m47s
(JST=UTC+9h) on January 8, 1992. The geocentric distance was 88,997
km. This is the first planet-swingby for a Japanese spacecraft.
During the approach, Sakigake observed the geotail. Some geotail
passages will be scheduled in some years hence. The second Earth-swingby
will be on June 14, 1993 (at 40 Re (Earth's radius)), and the third
October 28, 1994 (at 86 Re).

TOKYO (JAN. 21) KYODO - The Japan External Trade Organization
(JETRO) said Tuesday it has dispatched a mission of government and
industry experts to the United States to study the feasibility of an
international project for solar power generation in outer space.
Officials of the semigovernmental trade promotion body said
mission members will meet U.S. experts on solar power generation and
satellite technologies to discuss cost, technical, and organizational
problems in such a project.
The mission comprises a dozen officials representing the
government's Electrotechnical Laboratory and National Space
Development Agency of Japan, Toshiba Corp., and Mitsubishi Heavy
Industries, Ltd.
(Explanation of SPS deleted)
Possible problems in the project include reducing the cost of
launching solar cells, preventing environmental disruption that could
be caused by microwave transmissions, and solving technical
difficulties in receiving the transmissions, the officials said.
[Hmm...aren't these the same folks who sent a probe to the Moon
a couple of years ago? Somebody better grab them and say "lunar
resources" real fast. - KD]

1. INTRODUCTION
1.1 Foreword
The National Space Development Agency of Japan (NASDA) will launch the
Japanese Earth Resources Satellite-1 (JERS-1) by H-I launch vehicle (H24F)*
on February 3, 1992. This material provides an explanation of JERS-1 and its
launch.
(1) Launch program of H24F carrying the JERS-1, extending to second
stage/satellite separation phase and its confirmation.
(2) Satellite tracking and control program, including the launch phase in
which the JERS-1 preparatory operations for tracking and control are
carried out, as well as the initial phase consisting of injecting the
satellite into sun-synchronous subcurrent orbit. In the launch and early
orbit phase, the tracking and control network will be constructed by
Fairbanks, Kourou, Kiruna and Perth Stations in cooperation with NOAA
(National Oceanic and Atomospheric Administration of the U.S.), CNES
(Center National d'Etudes Spatiales=French National Space Research Center)
and ESA (European Space Agency) in addition to the Okinawa, Masuda and
Katsura Tracking and Data Acquisition Stations (TDAS) with the Tracking
and Control Center (TACC) located at NASDA's Tsukuba Space Center.
At each TACS, data on satellite's flight and functioning status are
acquired. These data are all sent to the TACC for processing, and
satellite control commands are sent to the satellite from the TACC via
TDAS. While the orbit and satellite control is undertaken by the TACC,
the operation management for the mission instruments is conducted by
NASDA's Earth Observation Center (EOC).
* Serial flight number from the first N-I launch vehicle at NASDA's
Tanegashima Space Center.
1.2 Objectives
The objectives of the mission are to launch the JERS-1 by H-I launch
vehicle. JERS-1 is an advanced earth observation satellite carrying newly
developed Synthetic Aperture Radar (SAR) and Optical Sensors (OPS).
In the sun-synchronous subrecurrent orbit, the satellite travels around the
earth in approx. 96 minutes and makes 15 revolutions a day. It takes a
different path in every revolution, but it comes back to the same position at
the same time of the day every 44 days. Therefore, it can periodically observe
the same point on the earth at the same time of the day. This means the
satellite covers the global land area for rexploration primarily, and land
survey, agriculture, forestry and fishery, environmental protection, disaster
prevention and coastal monitoring. JERS-1 is a joint development program
between the Science and Technology Agency (STA)/National Space Development
Agency of Japan (NASDA) and the Ministry of International Trade and Industry
(MITI). STA/NASDA developed the satellite bus, while MITI undertakes mission
instrument development.

2.3 Satellite
2.3.1 Outline
The purpose of the Japanese Earth Resources Satellite-1 (JERS-1) is to
develop Synthetic Aperture Radar (SAR) and Optical Sensors (OPS) and to
verify their functions and performances to establish an intergrated earth
resources observation system. JERS-1 will conduct observations mainly in
support of earth resources exploration, national land surveys, forestry and
fishery activities, environmental control, disaster prevention, and coastal
monitoring. The combination of SAR and OPS, and the Mission Data Recorder
provide JERS-1 with unique global land observation capabilities.
JERS-1 has been developed since 1986 as a joint project between NASDA
in charge of satellite bus development and launching, and the Ministry of
International Trade and Industry (MITI) responsible for mission instrument
development. It will be launched in February 1992 from the Tanegashima Space
Center by H-1 launch vehicle (two stages), injected into a sun synchronous
subrecurrent orbit at an altitude of 568 km and inclination angle of 98 deg,
and undergo tracking and data acquisition. JERS-1 will enable establishment of
common technologies for earth observation satellites and global observation
systems with emphasis on land areas.
2.3.2 Mission
JERS-1's mission is to accomplish the following objectives within two
years after lift-off:
(1) Conduct global observation by SAR and OPS
(2) Establish an intergrated earth resoures observation system
(3) Develop and verify functions and performance of the earth resources
observation instruments
(4) Develop and verify functions and performance of the earth resources
satellite bus system
2.3.3 Overall configuration and major characteristics
JERS-1, the largest satellite developed in Japan, has a synthetic
aperture radar antenna (11.9 m x 2.4 m) and a solar array paddle (8.0 m x 3.4
m). Its dimensions on orbit are 11.9 m in the direction of the flight path and
11.4 m in the transverse direction as shown in Fig.5 (not reproduced here).
JERS-1 is a three-axis stabilized satellite. The mission instrument such as
OPS and the antennas always face the Earth. The solar array paddle tracks the
Sun and generates the required electric power.
The satellite's configuration at lift-off is shown in Fig.6 (not
reproduced here). The satellite's main body is a slender rectangular solid
(3.1 m x 0.9 m x 1.8 m). The SAR antenna and the solar array paddle are
folded in for housing in the satellite fairing.

The first radio signal from the Japanese Earth Resources Satellite-1
(JERS-1/ FUYO-1) was respectively received at Kourou, Matsuda and
Okinawa Tracking & Data Acquisition Stations after the first orbit
revolution.
With the above confirmation of the signal reception, it is assumed
that the satellite has been injected into the planned orbit.
The JERS-1 has been denominated "FUYO-1" as its popular name. "FUYO"
is a Rose Mallow in English.
Also, it has been confirmed that the solar paddle deployment had normally
been conducted, and the satellite"s status has been in good condition.

the planned orbit, and the satellite has been in good condition.
JERS-1/H-I Launch Information No. 4
STATUS REPORT ON JERS-1 "FUYO-1" (February 12, 1992)
It has been confirmed that the solar array paddle of JERS-1/FUYO-1 had
been deployed as expected. Also, the satellite has been generating
electric power, and its attitude, etc. are in good condition.
Although a radio signal commanding the antenna deployment had been
sent from the Katsuura Tracking and Data Acquisition Station (TDAS)
around 21:38, February 11 (JST) when the satellite was at the 7th
orbit revolution, the telemetry signal indicating the first
(90-degree) deployment of the Synthetic Aperture Radar (SAR) antenna
among the three-step deployment was not confirmed.
As a result, the cause of the above phenomenon is presently under
investigation.

From Press Release "JERS-1/H-I Launch Information No. 5, February 19, 1992
Except the SAR antenna deployment, it has been confirmed that
the satellite had been in good condition through investigation made on
the condition at the time of the satellite orbit injection, its
attitude, temperature, electric power, etc. Also, NASDA decided to
take sufficient time to investigate the cause of the non-conformity
and to a solution. Consequently, a series of trouble-shooting was once
discontinued at that time.
The Ministry of International Trade and Industry (MITI) and
NASDA will establish a countermeasure committee to continue a series
of investigation and to coordinate the most suitable solution.
MITI will find the cause of the trouble and consider the
countermeasures based on the observation system's design, manufacture
and tests conducted in the past, by establishing a JERS-1 observation
system trouble countermeasure-tracking team.
NASDA will cooperate with MITI to conduct investigation and to
take countermeasures. In addition, it will consider the satellite
system and conduct necessary satellite operations. Moreover,
functional verification tests of the satellite bus equipments and the
other mission equipments other than SAR will be carried out as a part
of NASDA's tracking and control activities.

Subject: Forum agrees to develop global environmental satellite
Date: 12 Apr 92 01:22:55 GMT
KYOTO, Japan (UPI) -- American and Japanese political and
business leaders agreed Saturday to develop a global satellite system
to preserve the environment and help prevent natural disasters.
Participants at a bilateral conference outlined plans to work
with the governments of both countries to promote research and
development of the satellite.
Preservation of the global environment and support for the
former Soviet Union were discussed at the opening session of the
Japan-U.S. Leadership Council, a forum for discussion of global issues.
In the keynote speech, former Prime Minister Toshiki Kaifu
urged Japan and the United States to extend financial support for
developing countries and the former Soviet republics.
Former U.S. Secretary of Defense Frank Carlucci expressed
concern over the possible flow of nuclear technology out of the former
Soviet Union.
Carlucci, defense secretary from 1987 to 1989, called on the
United States and Japan to provide all-out support for moves toward
democracy in the former Soviet states.
U.S. representatives at the conference urged strong leadership
from Japan to deal with trade and economic issues.
James Jones, chairman and chief executive officer of the
American Stock Exchange, said Japan and France are hindering progress
in the Uruguay round of multilateral trade negotiations under the
General Agreement on Tariffs and Trade (GATT).
GATT Director General Arthur Dunkel has proposed all import
bans and quotas be replaced with tariffs that could be reduced
gradually, but Tokyo has rejected that plan. The administration of
Prime Minister Kiichi Miyazawa refuses to open Japan's long closed
rice market to foreign imports.

Subject: Gorbachev says Japanese support is vital
Date: 13 Apr 92 04:19:37 GMT
TOKYO (UPI) -- Former Soviet President Mikhail Gorbachev said
Monday support from Japan and other Western countries is vital to the
success of reforms underway in the Commonwealth of Independent States.
Gorbachev told Prime Minister Kiichi Miyazawa there is a
national consensus on introducing a market economy, but debate centers
on how to proceed, a Foreign Ministry official said.
In the 40-minute meeting, the former Soviet president cited
the tax system, assistance for low-income citizens and treatment of
manufacturers as areas requiring urgent attention.
Gorbachev arrived Saturday in Tokyo with his wife, Raisa, for
a 12- day visit to Japan at the invitation of a non-governmental
committee headed by former Prime Minister Yasuhiro Nakasone.
It is his first visit to Japan since a state visit last April,
when he became the first Soviet leader to set foot in Japan.
Gorbachev told Miyazawa that despite domestic turmoil in
Russia, President Boris Yeltsin is determined to improve bilateral
relations with Japan.
``I expect the president's visit will provide an opportunity
to introduce a new phase in bilateral relations,'' Gorbachev was
quoted as saying.
``It is important that Western countries including Japan
support the reforms in the CIS,'' he stressed.
Yeltsin is scheduled to visit in September, and the Japanese
have steadfastly maintained Russian recognition of Japanese sovereignity
over four islands is the key to making the trip a success.
Japan has refused to sign a peace treaty ending World War II
pending clear progress toward the return of the islands seized by
Soviet troops in 1945 and has maintained settlement of the bitter
territorial dispute is necessary before Japan offer full-scale
economic assistance to Russia.
Gorbachev's visit last year was dominated by Tokyo's demands
that the four northern islands off Hokkaido be returned.
While the official said Gorbachev and Miyazawa did not
specifically discuss the islands, Gorbachev told Miyazawa Russia's
internal problems are a matter of international concern because of
their impact on world stability.
Gorbachev also met with Emperor Akihito and Empress Michiko at
the Akasaska Palace.
During the weekend, the Gorbachevs visited Sensoji temple,
where they watched a game of ``tosenkyo,'' which dates back to the
18th century. Players take turns throwing a fan in an attempt to knock
over an object on a stand.
Encouraged by onlookers, Gorbachev tried his hand at the game
but only one of his five throws grazed the target.

of the Japanese Earth Resources Satellite-1 (JERS-1/FUYO-1) had been
deployed for 90 degrees through the analysis made at the NASDA Tsukuba
Space Center's Tracking and Control Center on the telemetry signal
received at 04:26, April 4, 1992, at NASDA's Transportable Tracking
Telemetry and Command (TT&C) Station located within the Swidish Space
Cerportation (SSC)'s Esrange, Kiruna, Sweden.
Upon receiving the signal, attitude and temperature data were also
analyzed at the above Tracking and Control Center in detail from April
4 through 5. As a result, it was verified that the above judgment was
correct.
The period of conducting the antenna's both wings' extention and its
off-nadir inclination will be decided after the detailed examination
to be carried out from now onward.
End.

History of Japanese MS Candidate screening
------------------------------------------
The Space Station named "Freedom" is a permanent evolutional and multipurpose
manned facility to be constructed in a low Earth orbit (approx. 400 km) using
the Space Shuttle.
This program was proposed by the U.S., and Japan has been participating in
it with the Japanese Experiment Module (JEM) under development as well as
the European Space Agency (ESA) and the Canadian Space Agency (CSA).
It is expected that the on-orbit facility assembly and the launch of JEM will
be started around 1995 and 1998 respectively, and the infrastructure-building
required to support the Station will be completed around 2000 in order to start
its operation.
NASDA recruited Japanese MS astronaut candidate(s) from July 1 through August
31, 1991, in order to select a few among from all the applicants. As a result,
372 persons applied for the position(s). The following is the screening history:
(1) 247 selected among form 372 as a result of submitted document-check in
September 1991.
(2) 53 chosen among from 247 as a result of the first screening (written
examination of language(English)) in October, 1991.
(3) 6 selected among from 53 as a result of the second screening (physical
examination, interview, etc.) in January, 1992.
The third (=final) screening was held in March 1992, and it included the
physiological aptitude test in NASDA's Tsukuba Space Center and physical
examination in NASA's Johnson Space Center.
As mentioned, NASDA is going to announce the Japanese MS candidate(s) on this
coming April 28, 1992., after through the final integrated evaluation including
interviews.
The MS candidate(s) to be selected this time will join the MS training course
expected for August 1992. The traing for obtaining basic knowledge and technique
to be a MS will last for a year. In case the candidate(s) is(are) authorized
as MS(s) after a year of training, he/she/they will be training on the operation
of the Space Shuttle, etc.
It is assumed that it will usually and approximately take 4 to 5 years until
he/she/they will be onboard the Shuttle; however, completing the above MS
training courses does not mean that he/she/they can automatically be onboard
the Shuttle.
The candidate(s) will continuously be training in the future on the assembly
and operation of the Station as astronaut(s) to stay and work there even
if he/she/they will not have experienced to be onboard the Shuttle in advance.

INTERIM REPORT ON IML-1 EXPERIMENTAL RESULTS
--------------------------------------------
I. Outline
This is to announce the interim results made on the two experiments proposed
by Japan and conducted in a Space Shuttle/Spacelab mission of NASA called
the International Microgravity Laboratory-1 (IML-1, STS-42).
The National Space Development Agency of Japan (NASDA) has been participating
in NASA's IML-1 mission with some European countries, Canada, etc.
NASA launched the Space Shuttle Discovery with IML-1 onboard from Kennedy Space
Center (KSC) at 09:53, January 22, 1992 (EST), (23:53, January 22, 1992, JST).
The 42 experimental themes, proposed by 11 countries including the U.S., Japan,
Canada and some European nations, were conducted for about 8 days under micro-
gravity environment using 16 experimental equipments developed by NASA, NASDA,
the Canadian Space Agency (CSA), the European Space Agency (ESA), the French
National Center for Space Studies (CNES), the German Space Agency (DLA).
The two experimental equipments called the OCGP (Organic Crystal Growth facility
with g-jitter Preventive measurement) and RMCD (Radiation Monitoring Container
Device) provided ny NASDA were loaded on the Spacelab. The experimental themes
are listed below:
1. Crystal Growth of Organic Superconductors in Microgravity
Principal Investigator (PI): Dr. Akio Kanbayashi (NASDA)
2. High Energy Cosmic Radiation Monitoring and Analysis of
Biological Specimens
PI: Dr. Shunji Nagaoka (NASDA)
II. Experiments and Results
1. Crystal Growth of Organic Superconductors in Microgravity
The purposes of the experiment were to grow large and high quality single
crystals of the organic superconductor under microgravity environment and
to acquire organic crystal growing technique.
The crystal growth experiment was carried out for about a week with a liquid
diffusion method under microgravity within the Spacelab, and the crystal of
organic superconductor was successfully grown there.
As a result, the structure and function of the above experimental equipment
under microgavity were verified. Also, it has been confirmed that a time
period required for crystal growth under microgravity could be shorten because
it took only a week to grow crystal of organic superconductors under micro-
gravity while it took three months to grow them with the same size on earth.
That is due to the fact that there is no thermal fluctuation caused by
convection or relative density difference within the microgavity environment.
Therefore, it was possible to shorten the time required to grow crystals
under microgravity compared with the earth environment by shortening the
distance between both the chambers of starting solutions among the three
chambers of the two cells where the crystals were grown and by using much
concentrated starting solutions.
It is also true that the high quality crystals of organic
superconductors were grown under microgravity. In addition to the
needle-type crystal stuck each other made on Earth, the ones grown
under microgravity consisted of metal-lustered type and flatboard types.
A lump of crystals as the above is considered extremely effective for finding
out the characteristics of organic superconductors and for analyzing the two-
dimensional superconducting mechanism and so on.
The crystals were grown in two cells with three chambers each. One cell had
a vibration damper while the other did not. The crystals grown in the cell
with damping were mostly bigger than the ones grown in another cell without
a vibration damper. Therefore, effects of damping were perceptible through
the experiment.
To investigate the influence of mivrogavity upon crystal growth, NASDA is
going to analyze the structure of the crystals grown under microgravity
and the characteristics of the superconductors in order to compare their
quality and characteristics with that of the crystals grown on Earth.
2. High Energy Cosmic Radiation Monitoring & Analysis of Biological Specimens
The objectives of the experiment are to investigate the biological effect of
cosmic radiation under a spaceflight environment and to contribute to the
development of radiation protection technology for manned spacecraft. Moreover,
the biological specimens used on the experiment, such as animal eggs, plant
seeds and bacterial spores, are presently being analyzed by NASDA.
The radiation monitoring experiment was conducted for about eight days, and
the radiation level reached inside the spacelab was actually and success-
fully measured.
Bacterial spores, maize (corn) seeds and shrimp eggs, which were attached to the
plastic track detectors and were loaded in the Radiation Monitoring Container
Device, were subjected to the cosmic irradiation in the Spacelab.
The expected amount of high energy cosmic radiation (HZE) was detected using
the plastic radiation detector (TS-16) developed by NASDA. Also, the particle
(corpuscular) beams having lower energies, which could not be measured with
the formerly used detectors, were successfully measured using the above
detector. Therefore, the function and characteristics of this device (RMCD)
developed by NASDA has been verified.
The radiation environment inside the Spacelab was measured. The Picture 4
shows a typical etch pit of the track of high energy particles (corpuscles)
observed on the surface of the plastic radiation detector used in the Spacelab.
Those particles turned out to have a linear energy transfer (LET) of approx.
1.5 GeV. cm2/g, entering into the surface of the above detector at an angle
of 39 degrees to it and then penetrated the monitoring container obliquely.
Through the analysis of the etch pit recorded in the solid detector, several
thousands of the high energy heavy particles (corpuscles) were found as
expected (they amounted more than 20,000 particles including the relatively
low energy nuclear species).
The three-dimensional trajectories of incident cosmic particles in the
monitoring container will be reconstructed by NASDA from now on based on
the etch pit analysis data obtained. Also, the hatchability of shrimp eggs,
the survival rate of bacterial spores around the etch pits, and the germi-
nation rate of the maize (corn) seeds will be analyzed and investigated by
NASDA to find out the effects of cosmic radiation upon these biological
specimens during spaceflight.

DEVELOPMENT SCHEDULE OF H-II LAUNCH VEHICLE
-------------------------------------------
The National Space Agency of Japan (NASDA) has been developed the
H-II launch vehicle as the new Japan's main Space transportation system.
NASDA has investigated the cause of trouble on the H-II 1st stage LE-7 engine
which occurred on June 18, 1992 at the NASDA's Tanegashima Space Center.
As the result of discussion, NASDA decided to change the H-II flight
schedule. The 1st flight was shifted from early 1993 to early 1994. The 2nd
flight was changed from summer of 1993 to summer of 1994 and for the third
flight in early 1995 from early 1994.
Development Plan of LE-7 Engine and H-II Launch Vehicle
1. Overview
NASDA has conducted the LE-7 engine firing tests over 200 times so far
and excellent results for the performance were obtained and good data for
durability was taken by achieving consecutively two full duration firing tests
with the same engine.
But, design change is required to take countermeasures of the trouble
happened on June 18, 1992. As the result, it is needed to reschedule the LE-7
engine development plan.
2. Current of trouble and its countermeasure
The engine performance including the specific impulse and engine start/
stop sequence were established. Full duration firing tests are required to
confirm the engine durability.
3. Cause of trouble and its countermeasure
(1) Trouble
Fire was seen out side of the engine at 5 seconds after ignition on
June 18. It is assumed that starting point of destruction is at the welding
part connected the main injector's elbow and liquid hydrogen turbopump.
(2) Cause of trouble
It is assumed that heat vibration over design value repeatedly
damaged the welding part and, cracks and breakages were occurred.
(3) Countermeasure
The following is under discussion as the main countermeasure.
i) Set of heat shield to protect the direct heat load into the welding part.
ii) Flatting of the welding part to protect the heat load into the limited
part.
iii) Change of heat treatment to improve the strength of the welding part.
Similar welding part on the engine will also be checked.
3. H-II Launch Vehicle Development Plan
The new H-II launch schedule is currently under discussion. Tentative
launch schedule is attached and further discussion will be done in detail.

Subject: GEOTAIL MISSION
Date: 22 Jul 92 06:45:06 GMT
Organization: Yokohama Science Center, Yokohama, JAPAN
* GEOTAIL *
The GEOTAIL spacecraft is Japan's largest scientific satellite
to date.
The purpose of the GEOTAIL mission is to study the mechanism
of input, transport, storage, release and conversion of energy in the
magnetotail of Earth. Part of the energy released produces very
beautiful emission of light known as Aurora seen in the Antarctica and
Arctic.
The GEOTAIL spacecraft carries on board the following
scientific instruments on board:
Electric field detector,
Magnetic field detector,
Low energy plasma analyzer and ion mass spectrometer,
Hot plasma analyzer and ion composition analyzer (from U.S.),
High energetic particle detector,
Energetic particles and ion composition spectrometer (from U.S.),
and Plasma wave analyzer.
The GEOTAIL spacecraft is a spin stabilized spacecraft
utilizing a despun antennas system. The diameter of the spacecraft is
approximately 2.2 meters with a height of 1.6 meters. The weight of
the spacecraft is approximately 1,000 kg including 332 kg of hydrazine
fuel. The design life is three years.
The GEOTAIL will be launched from KSC by making use of
Delta-II rocket into a 185 km circular parking orbit with an
inclination of 28.7 degrees. The upper stage will be ignited to boost
GEOTAIL into a translunar orbit. It is a unique point that the GEOTAIL
changes its orbit by using the swingby and maneuver technique.
Following are description of the phases of the GEOTAIL mission.
(1) Translunar Phase (until L+50 days)
Translunar phase is defined until the first lunar swingby,
which takes place on September 8-th, 1992.
(2) Distant Tail Phase (L+50 days to 1.78 years)
The GEOTAIL spacecraft will be first injected onto distant
tail orbit so that the orbital apsis should be aligned toward midnight
side of Earth. The orbital plane is almost same as that of the Moon.
(3) Trans-near-tail Phase (L+ 1.78 years to 1.85 years)
This is corresponding to the period from the last swingby to
the injection into near tail orbit. During this, two large amount of
corrective maneuvers are carried out. One of them is the orbital plane
change maneuver and the other is for the reduction of the apogee. The
insertion into Near Tail Phase is scheduled in May, 1994.
(4) Near Tail Phase (L+ 1.85 years to L+ 3.3 years)
The second half of the scientific observation will be
performed in the near tail phase, whose orbit is scheduled as 8 X 30
Re ellipse inclined 7.5 deg. to the ecliptic plane. The apogee is
directed to antisunward at the June solstice. This phase will last at
least one and half years.

of five satellites designed to explore the dynamic relationship
between the Sun's solar wind and the Earth's magnetic field and
various magnetosphere components, including the Van Allen belts and
the mission namesake P Earth's geomagnetic tail.
The spacecraft is expected to last four years and is equipped with
seven instruments that will be performing measurements on the various
magnetic field and particle components. In addition to its principal
payload, the Delta II second stage will carry a secondary scientific
instrument, the Diffuse Ultraviolet Experiment, which will measure the
diffuse glow from the interstellar medium and thereby help our
understanding of the evolution of this interstellar matter. This
experiment receives power from the Delta II second stage battery and
will be turned on only after the Geotail spacecraft has separated from
the second stage.

Subject: Geotail research satellite launched
Date: Fri, 24 Jul 92 10:26:16 PDT
CAPE CANAVERAL, Fla. (UPI) -- A $50 million Japanese satellite
was hurled into space Friday by a NASA rocket to study how particles
blasted away from the Sun interact with Earth's magnetic field.
The 126-foot Delta 2 thundered to life on time at 10:26 a.m.
EDT and quickly streaked away from the Cape Canaveral Air Force
Station, putting the satellite on course for a September flyby of the
Moon and a slingshot-like gravitational boost toward deep space.
The Delta's thundering ascent was normal and about 20 minutes
after liftoff the ``Geotail'' satellite safely separated from its
spent solid-fuel third stage rocket. Antennas and booms carrying
science instruments will be deployed later.
Project manager Kenneth Sizemore said the satellite came
through its ground-shaking launch in good shape with all systems
``go'' for a planned four-year mission.
If all goes well, Geotail will pass within 6,000 miles of the
Moon on Sept. 8, using the gravity of Earth's satellite to whip the
spacecraft into a new orbit that will carry it 860,000 miles from
Earth at its farthest point.
A second lunar flyby in November will change the orbit once
again, lowering the high point to about 400,000 miles.
Geotail was designed to explore different aspects of Earth's
``magnetosphere,'' the invisible bubble of energy surrounding Earth
like a giant doughnut that is defined by the planet's magnetic field
and shaped by the solar wind.
The appropriately named solar wind, made up of electrically
charged protons and electrons emitted by the Sun, buffets the
magnetosphere, distorting it into a teardrop-shaped region that
stretches away some 2.7 million miles from Earth's night side.
Over the next four years, seven instruments mounted aboard the
Geotail satellite will probe the tail of the magnetosphere to learn
more about how particles from the solar wind transfer energy into
Earth's environment.
Particles from powerful solar flares can disturb the
ionosphere, disrupting radio communications and causing trouble for
electrical power transmission on the planet's surface.
By studying the interaction between the solar wind and the
magnetosphere, scientists hope to learn how to predict such disruptive
effects.
``This is a very important problem that's a direct application
of the knowledge we derive from these types of missions,'' project
scientist Mario Acuna said at a news conference Thursday.
``Eventually, we would like to have (the) capability to say, 'we just
saw a solar flare on the Sun; what kind of risk does it represent to
us on the Earth in terms of disturbance to man-made systems?'''
The Geotail satellite is the centerpiece of a $160 million
program split evenly between the National Aeronautics and Space
Administration and the Japanese Institute of Space and Astronautical
Science.
The Japanese space agency paid $50 million for the satellite
and and another $30 million for experiment development while NASA
supplied the Delta 2 rocket, launch services and two of the seven
on-board experiments.

TOKYO (UPI) -- Officials Monday announced plans to blast Japan's
first-ever woman astronaut into space in 1994 aboard the U.S. shuttle
Columbia.
The National Space Development Agency said NASA Monday chose Chiaki
Mukai, 40, to serve as a payload specialist on a 13-day, July 1994 mission.
Mukai, a medical researcher trained in heart surgery, recently
provided ground support when the world's first Japanese professional
astronaut, physicist Mamoru Mori, went into space aboard the shuttle
Endeavor.
In the 1994 flight, Mukai will conduct experiments using a
microgravity laboratory developed jointly by NASA, Japan, the European
Space Agency, Canada, Germany and France.

Subject: Japan's first woman astronaut looks forward to ``gazing at the Earth''
Date: Mon, 19 Oct 92 23:14:16 PDT
TOKYO (UPI) -- Chiaki Mukai, the first Japanese woman picked
to take part in a U.S. shuttle mission, said Monday she looked forward
to realizing her ``dream of gazing at the Earth from outer space.''
NASA Monday selected Mukai, a 40-year-old medical researcher, to
blast off into space in July 1994 aboard the space shuttle Columbia.
``I feel honored to be picked as a crew member,'' Mukai told a news
conference following announcement of her selection. ``I want to devote
myself to training, while looking forward to realizing my dream of
gazing at the Earth from outer space.''
Mukai added that she hopes her participation in the Columbia mission
will encourage other women to pursue space voyages.
NASA plans to have Mukai conduct scientific experiments during a 13-
day space journey aboard Columbia.
She and two other Japanese nationals have been training with the U.S.
space agency since 1985.
``Seven years have passed in a flash,'' said Mukai, who NASA has
taught to be a payload specialist. ``I imagine I was picked because I
have enriched experience.''
Last month, Mukai served as a backup when another NASA trainee,
Mamoru Mohri, became Japan's first professional astronaut, traveling
into space aboard the U.S. shuttle Endeavor.
The zero gravity of space left Mohri's face swollen for three days,
but Mukai Monday said she planned to try out her own ideas in an attempt
to cut such post-space recovery time to one day.
Mukai added that she learned of her selection early Monday in a
telephone call from Japan's space agency.
``Bigger smiles have been on my face than usual since then,'' she
said.

Organization: Department of Astronomy and Astrophysics, Penn State University
Date: Wed, 11 Nov 1992 19:14:27 GMT
The original summary of Astro-D was roughly correct, but I can add
more detail and correct some errors. The original launch date of Feb.
5 has been postponed until Feb. 12 (pretty good for the total slip
over five years of development!). There will be substantial US
participation in the mission and in exchange the US community will
have an opportunity to compete for observing time. NASA's
Astrophysics Division will release an NRA (NASA Research Announcement)
on 15 Jan 93, due on 15 April, to allow US scientists to propose to
use 15% of the total observing time for US only work and another 25%
of the time for US-Japanese collaborations.
The instruments consist of four conical foil X-ray telescopes built by
Pete Serlimitsos of Goddard Space Flight Center, two X-ray CCD cameras
built by George Ricker of MIT (with Penn State Co-I's) and two gas
scintillation proportional counters built by Prof. Makashima of Tokyo
University. The four telescopes are coaligned and will simultaneously
point at the observing target, allowing both CCD cameras and both GIS
counters to collect data. Each mirror detector system has an
effective area around 400 cm^2, giving a total effective area greater
than Einstein, ROSAT or AXAF over most of the energy range. Moreover
the graze angle is smaller for these mirrors so they retain large
effective area up to 12 keV! (For reference the Einstein mirrors
dropped off at 3-4 keV, ROSAT at 2 keV and AXAF at 9 keV).
The major limitation of these mirrors is that they are not true
imagers (i.e. they are right cone segments and not paraboloid-
hyperboloid pairs). This limits the spatial resolving power to
1.3 arc min half power radius [although there is a sharp core to the
PSF which has been demonstrated to resolve point source 36 arc sec
apart.] The spectral resolution of the detectors is quite good. The
GIS has 8% energy resolution at 5.9 keV, and CCDs have 120 eV resolution
at 5.9 keV. The energy band pass runs from 0.4 keV up to 12 keV.
I don't know about press release material but an instrument
description will be included with the NRA in January of 1993.

Subject: Scientists to fly rockets by microwave in space
Date: 7 Dec 92 11:35:29 GMT
TOKYO (UPI) -- A Japanese research group is trying to control
microwaves in outer space in an effort to harness them as a future power
source, researchers told the Kyodo New Service Monday.
The group, led by Kyoto University Professor Hiroshi Matsumoto,
succeeded in flying a model airplane powered by microwaves last August.
They plan next to perform more sophisticated tests, such as controlling
the direction of microwave transmission, according to the researchers.
Matsumoto and Kobe University Assistant Professor Nobuyuki Kaya said
they hope eventually to use solar power satellites or space stations to
transmit microwaves to Earth for use as electrical power.
Matsumoto said the group in January will test the transmission of
microwaves 168 miles above Earth between two rockets equipped with
microwave amplifiers.
The rockets will send and receive microwaves as strong as those
produced in a household microwave oven and the researchers will try to
observe the effects outer space will have on the transmissions.
Matsumoto said he hopes the technology will serve as an alternative
power source by the middle of the next century, Kyodo reported.

Astro-D, the 15th scientific satellite and the fourth X-ray astronomy
mission of ISAS, will be launched by the M3S-II-7 roket from the ISAS
Kagoshima Space Center at 11:00 JST on February 12, 1993. Astro-D is
an advanced X-ray astronomy observatory which possesses unprecedented
capabilities in several respects. NASA has provided strong support for
this project.
Astro-D is equipped with the following X-ray imaging and
spectroscopic instruments: (1) Large-area X-ray telescopes with wide
wavelength (1-20 A) coverage, utilizing the multilayer thin-foil
conical optics technology developed by Dr. P. Serlemitsos of
NASA/GSFC, and prepared jointly by his group at GSFC, and the groups
of Nagoya University and ISAS.
(2) X-ray CCD cameras with superior spectral resolution which were
developed by the group of Dr. G. Ricker at MIT, and jointly prepared
by his group and the groups of Osaka University and ISAS. This is the
first time that X-ray spectroscopic CCDs will be used in orbit.
(3) Imaging gas scintillation proportional counters with medium
spectral resolution, developed by the groups of the University of
Tokyo and ISAS. In addition, an extensive set of computer software has
been developed by the joint team of Japanese (ISAS, Univ. of Tokyo,
Nagoya Univ., Kyoto Univ., Osaka Univ. and RIKEN) and U.S. (GSFC, MIT
and Penn. State Univ.) scientists.
With its high sensitivity and high spectroscopic capability, the
investigations with Astro-D will extend to virtually all classes of
astronomical objects, ranging from nearby stars to the most distant
quasars, on various current subjects: e.g., the physics of neutron
stars and black holes, supernovae and supernova remnants, the
evolution of galaxies and clusters of galaxies, the physics of active
galactic nuclei, and the origin of the cosmic X-ray background.
Through these investigations. Astro-D is expected to make important
contributions to the advancement of astrophysics and cosmology. A
significant portion of the Astro-D observing time will be made
available to international investigators.

Subj: Another dream realized: Dr. Chiaki Mukai's IML-2 flight decided
[Reprinted from NASDA Report No. 19 (March 1993). NASDA (National
Space Development Agency of Japan) is one of the two space agencies of
Japan. NOTE: No attempts have been made to correct any original
syntax errors.]
Another Dream Realized: Dr. Chiaki Mukai's IML-2 Flight Decided
"I am really very happy, and I feel I will have to work even harder
from now on." Dr. Chiaki Mukai was assigned to the Payload Specialist
(PS) on the Space Shuttle "Columbia" for the second International
Microgravity Laboratory (IML-2) in July 1994, thus expressed her
pleasure at the decision and ambition for the mission in the two years
hence. Dr. Mukai will be the first Japanese woman in space.
IML-2 is an international space experiment project led by NASA. It
will fly experiment equipment gathered from the participant countries
into the space experiment laboratory (Spacelab) aboard the "Columbia"
where crew members will conduct life science and material processing
experiments. Space experiments conducted will encompass a total of 80
themes proposed by the participant countries, including 12 themes
proposed by Japan. The flight is scheduled for 13 days which is
longer than "Fuwatto '92" conducted last September. [NOTE: "Fuwatto
'92" is the Japanese designation of the STS-47/Spacelab-J flight.]
In the IML-2 project, there are many science experiments which require
astronauts' expertise, such as cell separation by electrophoresis. PS
Mukai was selected because she has had experiment training as one of
the back-up PSs for the "Fuwatto '92" and has sufficient knowledge
about life science as a doctor of medicine.
PS Mukai expressed her high expectations for IML-2 because she feels
it is worth doing due to the numerous experiment themes and
possibility of comparing each participant country's technology level
through experiment equipment provided.
Mr. Richard J. Hieb, who was selected for IML-2 as payload commander
(PC), came to Japan with PS Mukai on October 27, 1992 and held a press
conference with her. Mr. Hieb is a shuttle mission veteran with two
flights, and he will be in charge of coordinating all conditions and
requirements concerning IML payload missions. Mr. Hieb spoke to the
press and answered their questions. He said, "Team work is very
important for the mission success, and I don't think there is any
problem in working with a Japanese PS." He expressed his resolve to
achieve success of the international mission, saying, "I think it is
very significant that personnel with different backgrounds in policy
and culture participate cooperatively in space programs."

ASCA Status Report No.1
February 25, 1993
The Astro-D satellite was successfully launched on February
20, 1993, at 11:00 JST (02:00 UT) from kagoshima Space Center.
The satellite was named ASCA (the Japanese characters for it
mean a "flying bird", or it is an acronym of an "advanced
satellite for cosmology and astrophysics"). The achieved
orbit has the following parameters:
Orbital period: 96.09 min.
Inclination angle: 31.10 deg.
Height of perigee: 523.6 km
Height of apogee: 615.3 km
The spin rate of the satellite at injection was ~2 rps which
was then dropped to 7.8 rpm by a yo-yo despinner. The spin
rate was further reduced by means of a magnetic torquing from
21 through 24 February to the intended rate of 0.9 rpm. A
correction of the spin axis orientation was also performed in
this period.
On 25 February, the satellite was put into a flat spin at a
rate of ~0.2 rpm in preparation for the solar paddle
deployment. This was implemented by activating reaction wheels
which absorbed the angular momentum of the satellite body and
shift the angular momentum vector to become perpendicular to
the satellite body (y-axis). Then. The solar paddles were
deployed at 02:05 UT. Generation of nominal power was
confirmed. Presently, the satellite is slowly rotating at a
rate of 0.17 rpm with the solar paddles pointed to the sun
("safe hold mode").
In-orbit verification of subsystems and the steps for
completing the final satellite configuration have been in
progress on schedule. The optical bench which is currently
folded short will be extended in early March. We continue
verificatin of the attitude control system, involving star
trackers, gyros, reaction wheels, and the on board computers.
Subsequently, we shall begin in-orbit test and tuning of the
X-ray detectors, i,e,. the X-ray CCD cameras and the imaging
gas scintillation proportional counters. Currently, we
anticipate to make ASCA ready for test observations before 20
March.

ASCA Status Report No.2
March 2, 1993
In-orbit tests of the ASCA satellite has been proceeding smoothly.
After the deployment of solar paddles on February 25, we began
tests of the computer-controlled attitude control system
involving the attitude sensors (star trackers, sun sensors),
gyro reference system, reaction wheels.
Results obtained so far demonstrate that two star sensors are
able to detect stars down to at least 7th magnitude. The
performance of the sun sensors, gyros, and reaction wheels
have been verified satisfactorily. The on-board computer
control has achieved a long-term attitude stability of the
satellite within 10 arcseconds. A satellite maneuver was also
performed and the function was verified.
On March 2, extension of the optical bench which had been
folded short inside the satellite was commenced at 04:21 JST.
The optical bench was successfully extended by 1.2 m in 4.5
min. and latched firm in position. The sun shade also opened
at the same time. Thus, the X-ray telescope system with a
focal length of 3.5m has been established. Following the solar
paddle deployment on February 25, we have now completed a set-
up of the final in-orbit configuration of the satellite ASCA.
In order to avoid condensation on the mirror surfaces., heaters
on the telescope cases were switched on on February 26. As a
result, the telescope temperature has been maintained at 5 deg -
10 deg C. No significant difference in temperature was observed
before and after opening sunshade, which might indicate that
the thin thermal-shield films (0.5 micron and 0.25 micron thick poly-
ester) remained essentially intact.
We will further continue fine tuning of the attitude control
system including star trackers, and gradually build up tests
of the X-ray detectors as scheduled.

March 15. 1993
The gas scintillation imaging spectrometers(GIS), two of the four
focal plane detectors, have been successfully put into operation.
Test of GIS started on March 12. High voltage supplies for
photomultiplier tubes were switched on on March 12, and those
for gas cells on March 13. The high voltage values have been
raised gradually up to the final operational level through
March 15. Both GIS counters are verified to behave normally.
Quick analysis shows that the instrument background rates are
roughly as expected. The background rate will be eventually
reduced to minimum by trimming several background rejection
logics in coming weeks.
As the above test was performed during the course of the
attitude control system test according to its own prioritized
schedule, no attempt was made to point the telescopes to a
Known X-ray source during this operation. No visible source
happened to be present in the field of view in the exposures
of about one hour in total. The GIS data will be accumulated
in coming days, and the instrument characteristics will be
examined further before the telescopes will be pointed to an
X-ray source to be chosen in the field near the present
telescope axis, which will occur around March 18.

The first light was successfully received from EXO 0748-676
with the Gas scintillation Imaging Spectrometers (GIS) on
March 18, 1993.
Observation of SN1993J by ASCA
On March 30, soon after all the instruments of ASCA became ready for
observation, an IAU telegram reported the detection of SN1993J in nearby
galaxy M81(NGC3031, about ten million light years away from the solar
system)in the direction of Canis Major. Brightening of SN1993J was
detected on March 28 and the magnitude reached 10.5 on March 31, which
is the brightest supernova since 1972 with the exception of SN1987A in
the Large Magellanic Cloud in 1987.
There has been almost no previous observation of such a bright supernova in
the X-ray band immediately after the explosion. ASCA changed its
observation schedule and pointed at the supernova on April 5 and 7.
ASCA detected intense X-ray emission from SN1993J. German X-ray
astronomy satellite ROSAT also made an observation and detected X-rays.
What is to be noted is that ASCA was able to obtain the X-ray image and
energy spectrum in a wide wave length band of 0.5 - 10 keV. This is the
first detection of X-rays from supernovae as early as 10 days after the
outburst.
The intensity of the X-ray emission from the supernova observed by ASCA
is about million times of the total luminosity of our sun, and the X-ray
spectrum is consistent with an assumption that the X-rays are from gas
of extremely high temperature of more than hundred million degrees. Such
emission is thought to be originate from the collision of the supernova
ejecta with the circumstellar material which was ejected from the
progenitor star just before the explosion.
It is expected that X-ray observation of the supernova will provide us
with important information such as what happened in the final stage of
the evolution of the progenitor star, evolution of temperature and
lonization state of the shocked material as the shock wave propagates,
and information on the newly born neutron star which may have been
formed at the center of the supernova.

Relations, ISAS).
1. History to Advent of 'Ohsumi'
Japan's activities in the field of space development began with
scientific observation and have been marked from the first by peaceful
goals. The pencil rocket was first planned by Professor Itogawa of the
Production Technology Research Institute of Tokyo University Institute
of Industrial Science and other volunteers from university and
government as an engineering research project following the resumption
of aeronautical research. But just three months before the experiment
was conducted something happened which had a great impact on the course
of space research in Japan. This was the decision to participate in the
International Geophysical Year (IGY) events with a domestic sounding
rocket.
What was of great technological significance up until that point in
time was the adoption of solid rockets.
At the time, it was conventional wisdom throughout the world that in
order to attain high altitudes a rocket should be a liquid-propellant
rocket in the tradition of the V-2, and that solid rocket technology, on
the surface of things, appeared to offer little future potential. It
must be admitted that, in conducting research toward the goal of
achieving the capability of reaching altitudes of 100km, as required for
the IGY, the problems which had to be faced as the project progressed
were greater than anybody expected. However, it should be emphasized
that there was some prospect for success. The most contributing factor
to achieve such goal, despite the prevailing situation, was the
development of composite propellants. Even though, in the end, the
100km altitude could not be achieved, the K-6 rocket was capable of
reaching 60km, and was used in the final six months of the IGY for
high-altitude air temperature and wind observations. This was the first
time Japan contributed to the international society with the use of
sounding rockets.
Building on the achievements during the IGY, the development of
sounding rockets proceeded steadily, which were eventually so matured
that the feasibility of launching artificial satellites was now studied.
Against this background and with the demand by space scientists all over
Japan, the Institute of Space and Aeronautical Sciences (ISAS) was
founded as part of Tokyo University in 1964. This institute was to be
used as a joint research institute for the purpose of achieving space
observations using space carrier vehicles. It is true that some bitter
setbacks were to be encountered before the advent of out first
satellite, but Japan's first artificial satellite, named "Ohsumi," was
launched in 1970.
Meanwhile, for a time in the latter half of the 1960's, much attention
was focused on the utilization of space in the fields of communications
and meteorological observations. This had an impact on the direction of
space research in Japan also, resulting in a flurry of activity to set
up a central organization to handle space development in application
fields, which finally resulted in the establishment of the National
Space Development Agency (NASDA) in 1969.
2. History of Satellite and Launch Vehicle Projects
It was natural that, with the founding of the National Space
Development Agency, studies should be done to come up with a basic
government policy on how in the future to handle the scientific
satellite projects which had been conducted at Tokyo University. As a
result, the scientific and application fields were separated, as we see
today, with these being handled, respectively, by the Institute of Space
and Aeronautical Sciences (ISAS) at Tokyo University and the National
Space Development Agency (NASDA), with the coordination of the Space
Activities Commission. Under the increasing influence of large-scale
applications programs, which began later, scientific satellite programs
gradually produced results and made successes commensurate with the
capabilities of Japanese rockets. With this background, the scientific
satellite program, in response to the demand by space scientists,
started to make steady progress toward more advanced observations.
Let us list here the scientific satellites up until the early 1980's
that made the most lasting impression: "Shinsei" and "Taiyo", which
carried out the observation of ionospheric anomaly associated with
anomalies in the terrestrial magnetism over South America; "Kyokko",
which succeeded in photographing UV images of the aurora; "Jikiken"
which conducted comparative observations of magnetospheric plasma
phenomena and aurora activities; "Hakucho" and "Tenma, which observed
X-ray stars using the modulation collimator; "Hinotori", which
contributed to the X-ray observation of the sun during periods of high
activity; and "Ozora", which was successful in the remote observation of
the atmosphere at mid-altitude. All of these satellites were small, but
they nevertheless produced outstanding results that attracted the
attention of space scientists all over the world.
At its foundation the National Space Development Agency was charged
with the mission of placing satellites of appropriate size into
stationary earth orbits. Judging it impracticable to quickly move to the
practical stage with only domestic efforts, NASDA decide to import
technology pursuant to the exchange of notes between Japan and the US in
1969. Thus development work began on the N-series rocket that was based
on transferred technology of Delta-series liquid-fuel rockets. The
Japan-U.S. Exchange Communique pertained not only to rockets, but was an
agreement concerning the acquisition of technology related to a broad
range o space equipment, and contained items that restricted the
transfer of such technology to a third nation. As a result, very great
restraints remained as we entered the era of space commercialization,
and the pros and cons of this communique are still debated. In any case,
the US technology transfer enabled NASDA to acquire liquid-fuel rocket
technology in a relatively short time frame, and in 1977 successfully
launched the geostationary engineering testing satellite "Kiku-II" with
the third N-I rocket. However, NASDA was still far from obtaining the
launch capability to meet the demands of those application satellites
between 300-350kg in mass. Thus NASDA had to commission two satellite
launches to the United States before the next generation N-II vehicle
was ready to go in 1981.
Prior to this (1978) the Space Activity Commission formulated the Space
Fundamental Development Policy Guidelines. In this document, the
importance of promoting the development of rockets using Japanese
technology was stressed, and this brought Japanese space activities to
another turning point. It was at this time that the development of both
the H-I, with its cryogenic second stage, and the H-II, with its
cryogenic first and second stages based solely on Japanese technology,
was initially conceived.
3. Age of Internationalization
In the past 10 years, the Japanese prowess in space development has
very quickly gained recognition internationally. This, naturally, is
due in part to the overall advance achieved by Japanese industry. But
another large factor has been the fact that the United States and Soviet
Union both slowed the pace of their space development for different
reasons.
First, in the field of space science, the probe to Halley's comet,
which approached our sun in 1986, were in many respects epoch-making. On
the domestic front, it was this development that was the occasion of the
founding of the Institute of Space and Astronautical Science.
Concurrently, Japan participated with the United States, Soviet Union,
and European nations in this project with two probes, and successfully
achieved her goals. This led not only to the development of the probe
vehicles, but also to major improvements in the M rocket launch vehicle.
The M-3SII rocket which resulted, is still the primary launch vehicle
used for scientific satellites. On the international front, U.S.-Soviet
antagonism was still quite severe, and it was little short of amazing
that U.S., European, Soviet, and Japanese organizations could all
cooperate and conduct projects successfully. This was regarded around
the world as an ideal example of international cooperation. Since then
international cooperation was also achieved with the participation of
Japanese and foreign scientists in the projects involving the satellites
which the Institute of Space and Astronautical Science subsequently
launched, namely the "Ginga," Akebono," "Hiten," and "Yohkoh," despite
their small scale. In July of this year, moreover, the magnetospheric
observation satellite "Geotail" was launched from Cape Canaveral in a
collaborative program with NASA.
In the practical field, the H-I rocket was completed at about the same
time. This vehicle was used to launch application satellites used for
such diverse purposes as communications, broadcasting, meteorology, and
ocean and land observations. This allowed Japan to gain more confidence
in its indigenous technology. However, the impact of globalization in
application fields are even more complicated. One of the problems is the
demand by the United States to open the satellite market for government
procurement concerning communication satellites and others. Such demand
was made under the Super 301, a part of the Omnibus Trade and
Competitiveness Act of 1988, which is often referred to in reference to
US-Japan trade imbalance. Japan fully accepted the US demand, and as a
result, it has been agreed that the government budget can cover only
those satellite projects for the demonstration of new technology or for
non-commercial and scientific research purposes. For the time being, the
largest international cooperative program in space is the Space Station
Freedom. The United States seems determined to implement this project
as a matter of national pride, and there can be no doubt but that this
project will have an extremely large influence on the future of the
application field. In any case, steady efforts are being directed toward
utilization of the space environment, and the manned space experiments
conducted this past September (1992) in the space shuttle Endeavor are
still fresh in our memories.
One example of the utilization of space environment is the joint
project SFU undertaken by the Institute of Space and Astronautical
Science (ISAS), Ministry of International Trade and Industry (MITI), and
National Space Development Agency (NASDA). The field of earth
observation has become of interest in recent years from the perspective
of environmental preservation. In this International Space Year, in
particular, we are seeing a lot of international activity that has been
organized under the banner of "Mission to Planet Earth." In this field
Japan is also contributing internationally with the launches of MOS-1a
and b, and JERS. This field is also of interest to the so-called
non-space nations in terms of remote sensing and is being carried out
with wide participation by researchers and agencies all over the world.
4. Perspectives
Now, in Japan, two rocket vehicles are under development, namely the
M-V and the H-II. The M-V is designed to launch scientific satellites
and the H-II to launch application satellites. The M-V can place a
payload of up to two tons into low earth orbit, and will be used in the
future for small missions to the moon and the planets and for small to
medium-sized earth missions. The H-II, on the other hand, is capable of
placing about two tons into geostationary orbit, and will be used in the
future for commercial launches.
Space research is becoming increasingly diverse and advanced, however
the scope of activities is likely to remain in the area covering from
the near-earth to the planets. Therefore, the development of M-V does
not immediately lead to larger probes and satellites. The fields of
infrared millimeter wave astronomy, VLBI astronomy, and lunar and
planetary probes, including sample-return missions employing robots, are
expected to develop rapidly in the future. In the field of engineering,
a future space transportation system is a research theme of major
concern. Projects currently underway include the MUSES-B which involves
space VLBI tests, PLANET-B in which the interrelationship between the
martian atmosphere and solar winds is being studied, and LUNAR-A which
will send a lunar seismograph to the moon.
In the practical field, development of a winged space shuttle "Hope" is
targeted for the purpose of transporting products from the Space
Station, as a part of the efforts to establish the infrastructure for
space operations. Stimulated by the finding of new merits of small
satellites, the development of J-1 with only solid stages is being
carried out, combining the solid booster of H-II and the upper stage of
M-3SII. Also planned are robot engineering test satellites to establish
the technology required for on-orbit rendezvous and docking techniques
and the "Comets" satellites for developing new technology oriented
toward future communications needs. A great deal of developmental work
is being focused on making earth observation satellites more
functionally sophisticated with higher precision, while the completion
of the overall observation system is certainly one of the major
objectives, as it is reflected in the proposal of WEDOS.
Sending a manned probe to Mars is, of course, a very attractive
project. The dominant view, of course, is that this should be pursued as
a joint international project. The present writer has no desire to argue
against this view, except to register my skepticism on the feasibility
of implementing such a project in the context of international
cooperation. I say this because of the difficulty I have in envisioning
a scenario in which the sum of the cost is estimated at the global
total, and then, the necessary funding is somehow raised in ways that
coincide with each nation's own projects. But let us suppose, for
argument's sake, that this is all possible. Such a project is still of
dubious significance unless it lasts forever. Therefore, we would first
have to increase the scale of space utilization and to implant by
various means the sound consciousness of the usefulnesses of space
activities in the mind of the general public.
The solar power generating satellite is drawing attention as a future
means to provide a non-polluting power source which lasts forever.
However, it would be of enormous scale. It would therefore, require a
lot of technological development, making it difficult to estimate its
full cost. There is no climate currently for supporting a global
approach to this project. According to forecasts based on global models,
however, after recognizing that we have already used up half of our
subterranean oil reserves, it is said that the environment will
deteriorate in the early 2000's, due to the increase in carbon dioxide
and other pollutants in the environment, so that world population will
begin to decline. In other words, the retrogression of modern
civilization will be staring us in the face if we do not alter our
present course. The only way to avoid such an embarrassing eventuality
is to abandon our oil-dependent civilization. It is in this context that
the costs of solar power satellites should be debated, and not on the
basis of current electric power costs. In any event, what we need to do
now is, in the first place, to steadily develop the requisite technology
for a future solar power satellite project and, in the second, to take
every opportunity we can to demonstrate developed technologies as much
as possible so that the general public could be convinced that it is
feasible and so that a solid support base can be formed. The Institute
of Space and Astronautical Science, albeit on a small scale, is steadily
making efforts in this direction. ISAS has organized researchers
nationally, and early in 1994 plans to conduct microwave electric power
transmission tests in the ionosphere using a sounding rocket, as part of
the activities of the International Space Year (ISY) sponsored by the
International Astronautical Federation (IAF). The importance of the
development of a low-cost mass transport vehicle such as the space plane
can surely be emphasized from this perspective.
Attempts on the moon would have slightly different meaning compared to
a manned Mars project. In the examinations at the international level,
too, the major significance of the lunar activities was found in
scientific observations or in building bases of experiments for many
purposes including scientific observations. Much experience has been
gained on the moon through the Apollo Program, and lunar activities are
included in the scope of near-earth activities. It is not too much to
say that the moon is another Antarctic. Taking into consideration that a
number of problems still remain to be solved for adapting man to outer
space environment, the effects of developing manned activities on the
moon would be beyond one's expectation. In our country, the Institute of
Future Technology is playing a key role in conducting technological
investigations related to the establishment of lunar base by private
companies (see also the report "iftec.93", 28 June 1993). The
precondition for building the lunar base is the development of an
effective transportation system. Unfortunately, such scenario is likely
to be considered as unrealistic since our country still does not have
such ambitious manned projects. It is my strong wish that scientists
evaluate the effectiveness of lunar activities from the right and broad
perspectives. Also, under the current circumstances, it is said that the
one which will have the highest demand in space is space tourism. The
value of the moon as the resource for tourism should be worth considering.
I believe that, in due course, space operations will become closely
linked to our daily lives, and bring us many wonderful benefits.

Subject: Launch of first made-in-Japan rocket postponed
Date: Mon, 31 Jan 94 7:01:31 PST
TOKYO (UPI) -- The National Space Development Agency postponed the
scheduled launch Tuesday of the first rocket made entirely in Japan, a
milestone in the country's space program, agency officials said Monday.
NASDA officials said approaching thunderclouds led to the
postponement of the launch from Tuesday until Wednesday at the earliest
from the Tanegashima Space Center on the southernmost island of Kyushu.
The 50-meter, two-stage launch vehicle is equipped with two large
engines utilizing liquid oxygen and hydrogen and is capable of sending a
two-ton class payload or multiple payloads into geostationary transfer
orbit at an altitude of 36,000 kilometers, or 22,320 miles.
The rocket will carry a Vehicle Evaluation Payload satellite, which
will confirm the launch performance of the H-2 as well as its
compatibility with the new range facilities at Tanegashima.
It will also carry an experimental vehicle called the Orbital Re-
entry Experiment, part of a program to prepare a Japanese space shuttle
to be launched around the year 2005.
Even before the launch, development of the H-2 raised speculation
that Japan may use the technology to build military missiles --
speculation the government denied.
Problems that included two engine explosions -- one of which
killed an engineer -- plagued the development of the rocket.
The cost of launching the H-2 has soared to 19 billion yen ($172
million), compared with 11 billion yen ($100 million) for the launching
of the European Space Agency's Ariane rocket.
In August 1991, a prototype engine blew up at Mitsubishi Heavy
Industries' rocket engine factory, killing the engineer. A second engine
exploded in June 1992.
Mitsubishi officials blamed the blasts on welding problems on engine
pipes.
Part of the reason for the quality problem was that ``development
engineers on the front were promoted to higher positions as the development
proceeded,'' said Akio Suzuki, a chief engineer at Mitsubishi.
``It was hard to maintain consistency as younger engineers
took over,'' he said.
A space development agency official also blamed an unrealistic launch
deadline. Development started in the mid-1980s.
NASDA Officials said Japan still lags behind the United States,
Russia, and Europe in rocket technology.

Japan has successfully launched its new rocket, the H-II. There was a
launch delay of about 20 minutes when a boat was discovered too close
to the launch area. No problems were encountered with the launch
itself, and the primary payload, OREX, a reentry test vehicle, also
seems to have worked fine. I'll post more details shortly.

Subject: Japanese rocket completes mission
Date: Thu, 3 Feb 94 22:53:06 PST
TOKYO (UPI) -- The first made-in-Japan rocket successfully
completed a two-hour space mission Friday delivering an unmanned
prototype space shuttle into a circular orbit, the National Space
Development Agency (NASDA) said.
After one pass around the Earth at an altitude of 450
kilometers (270 miles), the experimental space shuttle named OREX
splashed down as planned, 2 hours and 10 minutes after liftoff, about
460 kilometers (276 miles) south of Christmas Island in the mid-Pacific.
The agency spent 270 billion yen ($2.5 billion) developing the
H-2 rocket, which blasted off from Takegashima Space Center at 7:20
a.m. (local time), leaving a thick orange exhaust plume over the
southern main island of Kyushu.
The H-2 launch vehicle ``is a rocket of the highest standards
comparable to the main rockets of the European nations and the United
States,'' said NASDA President Masato Yamano.
The H-2 ``has been entirely developed by Japanese technology
and we are very proud of this fact.''
Japan has long been a laggard in aerospace due largely to
prohibitions imposed by the U.S. occupation forces after World War II
to prevent a resurgence of militarism.
The rocket enters a launch-services market crowded by the
United States, Europe, China and Russia. Many analysts expect the
commercial satellite market to start cooling off by 1997, when the H-2
begins carrying commercial payloads.
The lift-off was delayed for 20 minutes because a ship entered
the area where the H-2's solid rocket boosters were to plunge down
after the launch.
The rocket released the cone-shaped OREX six minutes after the
launch. It also delivered a 2.4-ton satellite into a high-altitude
orbit, where it will circle the Earth for four days.
``Today's successful launch has proved the feasibility of the
technology,'' Yamano said. ``We have achieved a major goal toward the
establishment of a key transporation system for the promotion of
diversified space development activities.''
The government stressed the H-2's non-military nature in
response to speculation that Japan may use the technology to build
military missiles.
The rocket ``turned space from a theater for Soviet-U.S.
military competition into a sphere of activity for people who want to
give wings to peaceful dreams,'' said Science and Technology Agency
Director Gen. Satsuki Eda.
Japan's energy program relying on plutonium and its rocket
development are devoted strictly to peaceful purposes, Eda said. Japan
will ``pay careful attention'' so that international concerns over
Tokyo's nuclear intentions need not arise, he added. The launch was
originally set for Tuesday but was delayed because of bad weather and
a faulty air duct that came loose.
The two-stage launch vehicle was equipped with two large
engines utilizing liquid oxygen and hydrogen and capable of carrying a
single two-ton payload or multiple payloads into geostationary
transfer orbit at an altitude of 22,400 miles (36,000 km), NASDA
officials said.
The first-stage engine, modeled on the U.S. space shuttle engine,
is one of the most sophisticated engines in the world, they said.
The rocket was developed by Rocket Systems Corp. (RSC), a
consortium of more than 70 companies led by Mitsubishi Heavy
Industries Ltd.
Problems that included two engine explosions -- one of which
killed an engineer -- plagued the development of the rocket.
As a result the cost of launching the H-2 soared compared with
11 billion yen ($100 million) for the launching of the European space
agency's Ariane rocket.
In August 1991, a prototype engine blew up at a Mitsubishi
factory, killing the engineer. A second engine exploded in June 1992.
Mitsubishi officials blamed the blasts on welding problems on
engine pipes.
Japan has built and launched rockets since 1975, but all
depended at least partly on U.S. technology.

OREX is hardly a prototype space shuttle! It's a simple object to test thermal
protection materials and concepts for an eventual shuttle. OREX bears no
resemblence (visually, structurally, or in virtually any other way) to Japan's
planned shuttle.
I don't mean to harp, but NASDA'a calling OREX a prototype shuttle is being
MUCH too generous to it.

Subj: NASDA H-II Information
Outline of H-II launch Vehicle
The H-II is designed to serve as NASDA's main space transportation
system in the 1990's to meet the demand for larger satellite launches
at a lower cost and still maintain a high degree of reliability. It is
capable of sending a single two ton class payload or multiple payload
totaling two tons onto geostationary orbit. the H-II is a two-stage
rocket equipped with two large solid rocket boosters (SRBs) on the first
stage for thrust augmentation
First Stage
The first stage of the H-II launch vehicle consists of the first stage
core vehicle equipped with the LE-7 engine and two solid rocket booster
(SRBs). The LE-7 engine is a liquid hydrogen/liquid oxygen engine with 86
tons of thrust (at sea level). The SRBs are polybutadiene composite solid
propellant boosters with 159 tons of thrust each (at sea level).
The guidance and control of the first stage is performed by the hydraulically
steerable nozzles of the LE-7 engine and of the SRBs controlled by the
Inertial Guidance Computer (IGC). Two auxiliary engines are also provide
to contro attitude.
Second Stage
The second stage of the H-II launch vehicle is equipped with the LE-5A liquid
hydrogen/liquid oxygen engine. The LE-5A engine is an improved LE-5 engine
(developed for the second stage of the H-I launch vehicle) and provides 12
tons of thrust (in vaccum). The guidance and control of the second stage is
performed by the hydraulically steerable nozzle of the LE-5A engine and the
reaction control system controlled by the IGC.
Guidance and Control System
The H-II launch vehicle employs a strapped-down inertial guidance an
control system. The system consists of the Inertial Measurement Unit (IMU)
which uses three ring laser gyros and the IGC. The inertial guidance and
control system enables the H-II launch vehicle to correct errors auto-
matically and to maintain the planned orbit without commands from the ground
station.
Payload Fairing
The payload fairing protects the payload from the severe launch environment
and from contamination on the ground.
Principal specification of the H-II
Overall length 50
Diameter 4
Total mass 260t (payload not included)
Guidance system Strapped-down inertial guidance system
Outline of Orbital Re-entry Experiment (OREX)
The OREX flight experiment is part of the research for the H-II
Orbiting Plane (HOPE).
Its purposes are to contribute to HOPE development by accumulating
experience in designing and producing a re-entry vehicle and acquiring
re-entry data which is difficult to acquire in ground experiments.
The OREX vehicle will be launched and inserted into orbit by H-II
rocket. It will then re-enter the atmosphere after one revolution.
The vehicle will collect experimental data during re-entry, transmit it
after re-entry, and splash down in the Central Pacific Ocean.
The OREX project is being conducted in cooperation with the National
Aerospace Laboratory (NAL).
Shape: Blunt-cone shape, Nose radius 1.35m, Diameter 3.40m, Height 1.46m
Weight: Approx. 865kg at launch, Approx. 761kg at re-entry
The OREX vehicle will be launched at 7:00 AM on February 1, 1994 (JST).
Outline of Vehicle Evaluation Payload (VEP)
The VEP is planned to be dual-launched with the OREX Vehicle
by the first H-II rocket in the winter of 1994. The purpose
of the VEP is to measure orbital parameters of injection by
the H-II rocket and mechanical environment at launch.
Weight: Approx. 2.4t

I just got off the phone with a friend who has good connections in
Japan. He sent off a summary of the recent H-II launch abort to
s.s.news. It's been slow in showing up so I thought I'd post some
info here in the meantime.
As some people may have already heard, the attempted second launch of
Japan's H-II was aborted a few days ago. The mission was to have
carried the ETS-6 expermiental technology satellite. Launch countdown
went exactly as planned right up to liftoff, with the LE-7 engine
working perfectly. However, the two solid rocket boosters both failed
to ignite, so the rocket did not actually lift off the pad. The
engineers are happily pointing out that the LE-7, which has been
having problems in tests, worked fine. The flip side is that having
both solids fail to ignite is very embarassing (though having only one
ignite would have been more so). It is very easy to ignite a solid
booster, so the odds of having two hardware failures seem rather low.

1.Overview of the H-II Launch Vehicle
1.1 Purpose, particulars and development plan
The National Space Development Agency of Japan(NASDA) has developed
and launched the N-I, N-II, H-I and H-II launch vehicles, all capable
of launching spacecrafts.
The N-I is a three-stage vehicle capable of putting a 130-kg payload
into geostationary orbit. The N-I launch vehicle was developed to have
launch capability for medium-altitude as well as geostationary
satellites. NASDA succeeded in launching the Engineering Test
Satellite I (ETS-I) called "Kiku" on September 9, 1975. A total of
seven satellites were launched between 1975 and 1982.
Based on the technology obtained from the N-I launch vehicles,
the N-II was developed for practical use in launching satellites.
The N-II is a three-stage vehicle with a capability of launching
a 350-kg geostationary satellite. NASDA succeeded in launching
the Engineering Test Satellite IV (ETS-IV) called "Kiku-3"
on February 11, 1981. A total of eight satellites were launched
between 1981 and 1986.
The H-I launch vehicle was developed to meet the growing needs to
launch larger satellites as well as to improve vehicle performance
by using independent Japanese technology. The H-I is a three-stage
vehicle capable of launching a 550-kg geostationary satellite.
NASDA succeeded in launching the Experimental Geodetic Satellite (EGS)
called "Ajisai" on August 31, 1986. A total of 13 satellites
(including shared payloads) were put into operation with nine launch
vehicles between 1986 and 1992.
The H-II launch vehicle has been developed to meet the demands for
larger spacecraft launching in the 1990's. The H-II is a two-stage
vehicle capable of delivering a 2-ton class satellite into
geostationary orbit. Its basic configuration, target performance and
development plan were approved by the Space Activities Commission
(SAC) in 1984. Following its preliminary development tests in 1985,
NASDA commenced its actual development in 1986. The initial goal of
development was to launch the first H-II launch vehicle in 1991.
The basic policies of development are as follows: first H-II launch
vehicle in 1991. The basic policies of development are as follows:
(1) Develop the launch vehicle with autonomous Japanese space technology.
(2)Reduce both development period and costs by utilizing developed
technologies to a maximum extent.
(3)Develop a vehicle able to be launched with the current site
conditions of Tanegashima Space Center.
(4)Use design criteria that allows sufficient performance for both
the main systems and subsystems. Ensure that development will be
carried out properly, taking safety into account.
Development of the first-and second-stage structures, second-stage
engine (LE-5A), solid rocket boosters (SRBs), payload fairing and
onboard electronic equipment proceeded satisfactorily.
However, it turned out that more advanced technology was required for
development of the main engine (LE-7) for the first stage.
Therefore, the development plan was reconsidered in 1989 and 1992,
and launch of the first H-II was rescheduled from the originally
planned year of 1991 to the winter of 1993.
Between 1991 and 1992, ground system tests were carried out using
the H-II ground-test vehicle to "confirm the overall functions of
the vehicle" and "confirm consisitency between the vehicle and ground
facilities and the launch operation procedures."
From 1992 to 1993, captive firing tests for the first-stage engine
were carried out to "confirm consistency between the LE-7 engine
and the first-stage propellant feed systems and their functions."
After that, final tests for qualificaton of the LE-7 were completed
satisfactorily, and NASDA commenced launch processing for
the first H-II test vehicle at Tanegashima Space Center in October
1993.The first launch was made at 7:20 AM on February 4, 1994,
successfully placing the Orbital Re-entry Experiment (OREX) and the
Vehicle Evaluation Payload (VEP) into the planned orbits.

4.1 Outline of ETS-VI
The purpose of the Engineering Test Satellite-VI(ETS-VI) is to
establish bus technology for large-scale geostationary three-axis
stabilized satellites necessary for the development of future
application satellites as well as to develop advanced satellite
communications technologies such as fixed satellite communications
mobile satellite communications and intersatellite communications.
It is slated for launch from the Tanegashima Space Center by the
second H-II test vehicle on August 17, 1994.
ETS-VI was started its preliminary design in 1987 and, after having
the system proto-flight tests at the Tsukuba Space Center, was moved
into the Tanegashima Space Cneter in March 1994.
ETS-VI features one of the leading large-scale satellites in the world
in terms of technology and on-board payload capacity, etc..
After the launch, it will be kept in geostationary orbit at the
Longitude 153.8 deg East.
Three-month checking of the satellite functions will be made before it
starts a mission operation.
4.2 Objectives of ETS-VI
Major objectives of ETS-VI are as follows.
(1)Establishment of bus technology for large-scale geostationary
three-axis stabillized satellite. -to establish the technological base
necessary for realizing 2-ton-class geostationary three-axis
stabilized application satellites in the 1990's and at the beginning
of the 21st century.
(2)Development of advanced satellite communications technologies and
their experiments in orbit. -development and orbital experiments of
highly advanced satellite communications technologies such as
intersatellite communications, fixed and mobile satellite
communications, supporting the future information-oriented society as
well as a wide range of human activities in space.
(3)Development of bus experimental equipment and its experiment
in orbit. -to conduct experiment of bus equipment in space, such as
nickel-hydrogen battery and electrothermal hydrazine thruster which
will be useful for future large-scale spacecraft.
4.3 Feature of ETS-VI
(1)large-scale payload capability
(2)ion engine for north-south staion keeping
(3)bipropellant apogee engine
(4)high precision and fault tolerance in attitude control system
(5)a number of on-board experimental equipment
(6)advanced satellite communications equipment
(7)large capacity of electric power
(8)long life and high reliability design
4.4 Configuration and Characteristics
4.4.1 System Sumary and Major Characteristics
ETS-VI is a large-scale satellite equipped with solar array paddles on
the north and south sides of its rectangular body (3.0 mA~2.0
mA~2.8m ),an antenna tower on the Earth-oriented panel, main
reflectors with aperture diameters of 3.5 m and 2.5 m for the fixed
and mobile satellite communication experiment, a phased array antenna
for S-band intersatellite communication, a K-band intersatellite
communication antenna mounted on two-axis gimbals within platform, and
laser communications equipment.
The satellite body is divided into a 2 m high mission module on the
top(the antenna side) that carries the experimental equipment such as
the transponder, and a 0.8 m high bus bay at the bottom that carries
the bus equipment.
One pair of ion engines used for north-south station keeping of
the satellite is installed on each of the east and west sides.
At launch, a liquid apogee propulsion subsystem module is mounted
on the bottom side of the satellite body, but it is separated from
the satellite body after injection into drift orbit.
ETS-VI, which will be kept in geostationary orbit, has a large shape,
measuring 30 m in the north-south direction, 9.3 m in the east-west
direction, and 7.8 m in the Earth direction, with an initial weight
in orbit of about 2 tons.

| While the H-II apparently worked perfectly, it seems that the
satellite's Apogee motor failed to work. They tried twice, and then
declared that Apogee motor a failure. I don't know if the satellite is
usable in its current orbit for anything at all. (Report from the

>From NASDA Press Release:
August 31, 1994
NASDA HQ, TOKYO
The National Space Development Agency of Japan (NASDA) launched the
Engineering Test Satellite-VI (ETS-VI) by the H-II Launch Vehicle Test
Flight No. 2 from NASDA Tanegashima Space Center on August 28, 1994.
NASDA conducted the apogee engine firing at 02:19 PM on August 31 (JST) to
change the orbit of the ETS-VI. However, the thrust level of the apogee engine
firing was much smaller than expected and the condition of the apogee engine
was not recovered in spite of the following recovery efforts. NASDA abandoned
the satellite injection into the geostationary orbit.
Though the original experimental plan can not be attained, NASDA will take
every possible measures to make several experiments available in the transfer
orbit to verify the bus technology for large-scale satellite and the advanced
satellite communications technologies. Furthermore, NASDA will make a thorough
investigation of the cause of the trouble.
-------
September 1, 1994
NASDA HQ, TOKYO
NASDA made a successful separation of Liquid Apogee Propulsion Subsystem
(LAPS) of ETS-VI, which failed to change the orbit from the transfer to the
geostationary, at 00:10 AM on September 1, 1994 (JST) by a command from
NASDA's Tracking and Control Station in Goldstone, CA.
The condition of the satellite is normal after LAPS separation.
The orbit determination is as follows:
Apogee Altitude: 38,715 km
Perigee Altitude: 7,791 km
Orbit Inclination: 13.1 degree
Period: 14 Hours 06 Minutes
Schedule of events hereafter such as full deployment of Solar Array Paddles,
Deployment of Antenna, three-axis stabilization, etc. will be announced as
soon as possible.
